OGLAS — Off-Grid Local Alert System

Analog

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS analog node is the workhorse. It’s a battery-powered wireless device that wakes up, reads an analog input, sends the value, and goes back to sleep. Same firmware drives sensors for soil moisture, light, voltage, level — anything that comes out as a 0–3.3 V signal.

What it does

On each wake cycle:

Reads an analog input (12-bit ADC, 0–3.3 V).
Sends the reading to your hub.
Waits for confirmation.
If no confirmation, sleeps briefly and retries so the hub knows the reading is stale.
Once confirmed (or after retry limit) deep-sleeps for the configured interval.

The reading counter and last value survive deep sleep so a power-cycle doesn’t lose history.

Door / Gate

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS door / gate node knows two things: when something is open, and how to open it on command. A paddock gate, a shed door, a depot roller door — same node, same wireless link as the rest of your sensors.

What it does

Detects open/closed state — a reed or limit switch on the frame trips the device, which immediately reports the state change to your hub.
Opens on command — a signal from the hub (or a button in your vehicle) pulses an output that drives your motor or relay. You can open a single door/gate or every one at once.
Reports when it’s done — confirms back to the hub so you know the action ran.

The matching bell can ring a buzzer indoors the moment it trips — works as well on a farm entrance as on a yard gate or a shed left open overnight. See Monitoring and alerts.

LoRa Hub

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS LoRa Hub is the simplest way to start, and the default for most sites. It sits on a shelf in the shed or office, listens for sensor messages over long-range LoRa, and logs everything to local storage. No display required — point Local on a laptop, SBC, or NAS at it and you’ve got the lot.

What it does

Listens for sensor readings from every device in range, confirms back so the sensor knows it got through.
Listens on short-range wireless as well — a shorter-range link that uses less airtime, so nearby sensors save battery and leave the long-range channel clear for the ones that need it.
Stores readings locally to flash / SD / a connected host, in a format you control. Your data, your formats, your backups — see Your data is your data.
Forwards commands — when you want to open a gate or ring a bell, the hub sends the instruction to the right device and collects the response.

Hardware

Purpose-built wireless hardware with long-range LoRa radio. Compact, low-power, designed to sit on a shelf and run 24/7.

Power Management

Mon, 01 Jan 0001 00:00:00 +0000

Power management sensors read the system that keeps everything else running: your solar and battery setup. They’re sensors like any other in OGLAS — they measure something off the world and report it — but what they measure is power production, battery state, and load, and they make it available to your hubs, your dashboards, and your smart switches.

The first of these reads a Victron MPPT.

Victron MPPT

If your power comes from solar — most off-grid sites — the Victron power-management sensor pulls production data into the same dataset as everything else.

Smoke & Gas

Mon, 01 Jan 0001 00:00:00 +0000

A smoke alarm nobody can hear from the house is no alarm at all. The OGLAS Smoke & Gas sensor puts detection in the buildings that matter on a remote site — and gets the alert to you wherever you are.

What it does

Detects smoke — early-warning detection in sheds, workshops, and stores well away from the house.
Detects combustible gas — LPG, methane, and the like, around gas stores and pump houses.
Detects toxic gas — carbon monoxide in a generator shed or workshop.
Alerts immediately — straight to the bell, every bell on site, and (with Cloud) a push to your phone. This is the message that doesn’t wait.

Honest scope

This is monitoring and early warning for remote, unattended buildings, not a replacement for the certified smoke alarms your dwelling is required to have. It covers the sheds and outbuildings those alarms never reach.

Vehicle Track

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS Vehicle Track wires into the accessory rail of a vehicle — or any engine on the site — and logs every run. Trips, hours, fuel-time, GPS, battery state. Equally happy on a tractor, a ute, a forklift, a golf cart, a generator, or the irrigation pump’s diesel — a single asset or a whole fleet.

What it does

Power up = new run — each start records a fresh log entry at zero minutes, with a GPS fix and the starting battery voltage.
Counts minutes while running — re-persisted to flash every minute so a flat battery never costs more than 60 seconds of log.
Records a path, not just a duration — periodic GPS waypoints during the run (configurable interval), so you have where it went, not just for how long.
Captures battery voltage at start, periodically during the run, and at shutdown. Lets you spot a failing alternator before the day it doesn’t crank.
Reads the engine via OBD-II (optional) — on vehicles with an OBD-II port: RPM, coolant temp, fuel level, speed, and fault codes (DTCs), logged with the run.
Measures how it’s driven via an IMU (optional) — harsh use, idle vibration, and tip/roll angle for a rollover warning on a tractor, quad, or forklift.
Back-walks unsent runs on each start — sends the most recent run first, waits for confirmation, then walks back to the next unconfirmed run until it hits one already recorded.
Rolls over — fixed ring buffer of 500 records by default; newest id overwrites oldest slot.
Shows alerts in the cab — sensor and site alerts appear on the on-board display while you’re in the vehicle. Low water, fence down, gate left open, engine service due — see alerts in the cab below.
Identifies the operator (optional) — a short list of names selectable at start, so the run log records who drove, not just what drove.
Triggers external devices — built-in button or configurable proximity rules can open a gate, ring a bell, or activate any other OGLAS device.

OBD-II and IMU

Two optional add-ons turn Vehicle Track from a run-logger into a condition-logger:

Water Trough Level

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS Water Trough Level sensor is purpose-built for stock water — the troughs scattered across paddocks where animals depend on a working float valve and a charged pump. If a trough goes dry, you find out before the animals do.

What it does

Reports level periodically — default interval an hour; configurable down to minutes when you’re commissioning, back up to once a day when you trust it.
Raises an immediate out-of-water alert when level drops below a configured threshold — independent of the reporting interval. This is the message that matters and it doesn’t wait.
Includes GPS coordinates with each reading, so the hub knows which trough this is without you having to track node-id-to-paddock mappings by hand.
Reports battery voltage so you can replace the battery on schedule, not on failure.

Why GPS

A property with twenty troughs is a labelling nightmare. Without GPS:

Your data is your data

Mon, 01 Jan 0001 00:00:00 +0000

The single biggest design decision in OGLAS is that your data never has to leave your site. The hub logs every sensor reading to local storage, and Local keeps the full record on your hardware. There is no OGLAS cloud account, no monthly fee, no “premium tier” that holds the last 90 days of your history hostage.

What this means in practice

No subscription. Buy the hardware, run it, done. There’s nothing to renew.
No vendor lock-in. Readings are stored in plain text and easily-parsed binary formats. If you want to move them to a different system in five years, you can. If we disappear in five years, you still have everything.
No third-party account. No login, no email-and-password to forget, no app store dependency.
No telemetry. The hub doesn’t phone home. Updates are pulled when you choose, not pushed at 3am.

What we mean by “local”

The hub writes to its own flash, an SD card, or a host you connect (USB, network share, NAS — your choice), and Local runs on your own SBC or laptop. If you want an off-site copy or a remote view, that’s the optional Cloud half — on your own server, your own terms. The decision of where the data goes is always yours.

Bell

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS bell is the noise-maker. It sits in the house, the office, the shed — wherever you want to hear about things — and turns sensor activity into sound.

What it does

There are three ways the bell rings:

Pattern match on incoming sensor activity — by default, when the gate opens, the bell triggers a single buzz. Rate-limited so a flaky link can’t replay the same event into a buzz-storm.
Direct ring command — a single, immediate buzz with no cooldown. Use this for manual or scripted pings from the hub.
Alarm mode — a repeating tone for a configurable window (default 60 s). Re-issuing the command extends the window.

Plus remote mute/unmute, and an on-board mute button that toggles silence with a fast-flashing LED to show the bell is alive but quiet.

Engine

Mon, 01 Jan 0001 00:00:00 +0000

An engine that never moves still wears out — and the backup generator nobody logged is the one that won’t start when you need it. The OGLAS Engine sensor brings the Vehicle Track run-log to fixed engines: generators, pump engines, compressors, anything that runs in place.

What it does

Detects runs — from the engine’s accessory output, a vibration sensor, or current on the load. Every run is logged with start time and duration.
Counts hours — accumulated run-time per engine, so service intervals are by hours, not by a date someone guessed.
Trends battery and starting — for engines that fail to crank, the battery is usually the culprit; trend the voltage and you’ll see it coming.
Flags exercise gaps — is the backup genset actually being run monthly, or has it sat idle since spring?
Raises service alerts — hours-since-service past the limit rings the bell or pushes a notification.

Why it’s its own sensor

It shares the run-log engine with Vehicle Track — the difference is the trigger and the fact that GPS doesn’t move. For anything with a cab and a journey, use Vehicle Track; for a genset bolted to a slab, use this.

Mesh Hub

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS Mesh Hub is for sites where a straight radio line from sensor to hub doesn’t exist. Instead of every device needing to reach the hub directly, devices (and dedicated repeaters) relay for each other — a reading hops node to node until it lands at the hub.

When you want mesh

Broken line-of-sight — a hill, a steel shed, a tree line, or a fold in the ground sits between a sensor and the hub.
Sprawling sites — the far corners are past the range of a single LoRa link, but there are devices in between to carry the signal.
Resilience — if one path goes down, traffic finds another way through the mesh rather than a sensor simply going silent.

What it does

Collects from the mesh — confirms readings and logs them locally, exactly like the LoRa Hub, but the messages arrive via one or more hops.
Self-heals — nodes discover neighbours and re-route automatically as devices come and go or conditions change.
Mixes sensors and repeaters — most OGLAS sensors can carry mesh traffic for their neighbours; add low-cost repeaters to bridge the gaps that have no sensor of their own.

Trade-offs, honestly

Mesh buys coverage at the cost of a little latency and power — each hop adds a small delay, and relaying nodes can’t sleep as deeply as a leaf sensor talking straight to a hub. For most sites that’s a fair trade for reaching the spots a single link can’t. If you can see the hub from everywhere, the LoRa Hub is simpler.

No telco dependency

Mon, 01 Jan 0001 00:00:00 +0000

A lot of “smart” sensors assume your gate, your tank, and your shed all have decent 4G coverage. Most off-grid sites don’t. OGLAS doesn’t need them to.

How sensors talk

Every OGLAS sensor talks to the hub over long-range wireless — the same class of low-power radio used for everything from livestock trackers to satellite uplinks. Range is measured in kilometres, not metres. Power draw is low enough to run for a season on a single battery.

Noise

Mon, 01 Jan 0001 00:00:00 +0000

Sound is a surprisingly good sensor. The OGLAS Noise sensor reports a sound level — not a recording — so you can tell, from anywhere, whether something is running, alarming, or happening when it shouldn’t be.

What it does

Measures sound level — ambient dB over time, with thresholds you set.
Detects “running” — a pump, compressor, or generator is audibly on; pair that with Power Monitoring to confirm it’s working.
Detects “alarming” — another alarm sounding (a separate smoke alarm, a reversing beeper, a siren) becomes an OGLAS alert.
Detects “activity” — noise in a yard or shed that should be quiet overnight.

It reports a level and threshold crossings only — no audio leaves the device, which keeps it private and keeps the data tiny — see Your data is your data.

Smart Switch

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS Smart Switch is the active end of the network. Where the other sensors measure and report, the Smart Switch acts — turning a load on and off based on conditions you’ve defined, and reporting back not just whether it switched but whether the load is actually working.

What it does

A Smart Switch decides whether to be on or off using one or more of:

Power-management data — reads incoming watts, battery state, and load from a power-management sensor (e.g. Victron MPPT). Run the relay on stable solar surplus.
Sensor data — subscribe to readings from other OGLAS sensors. Tank dropped below 200 mm? Soil moisture below threshold? Battery bank above 90 %? React.
Web / API data — when Wi-Fi is available, pull from a local server, MQTT broker, or HTTP endpoint. Used for off-property triggers that need external data.
Weather data — forecast and current conditions from a weather API. “Run only when the next 6 hours are clear” is one rule that uses this.

Multiple inputs combine with AND/OR rules in the device config. None of this requires a cloud account — see Your data is your data.

Tank level

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS tank level sensor reports how much water you’ve got, in millimetres, on whatever schedule you set — from once a minute to once a day.

Why it matters

If you run on tank water, the difference between “fine until next month” and “the pump’s run dry overnight” is the level of the tank you forgot to check. OGLAS makes it the hub’s job to remember instead.

Weather

Mon, 01 Jan 0001 00:00:00 +0000

The forecast for the nearest town is not the weather in your back paddock. The OGLAS Weather sensor is a station that reports your conditions to your own hub — and feeds the rules that act on them.

What it does

Temperature & humidity — ambient conditions, logged continuously.
Barometric pressure — the leading indicator of a change coming through.
Rainfall — a tipping-bucket gauge totalising what actually fell on you.
Wind speed & direction — for spraying windows, fire days, and structure-load awareness.

All of it lands in the same dataset as your other sensors, so “it rained 12 mm” sits next to “the tank rose 40 mm” and “the soil came up to field capacity”.

Electric Fence Active

Mon, 01 Jan 0001 00:00:00 +0000

An electric fence that’s stopped pulsing is just a fence — and animals work that out fast. The OGLAS Electric Fence Active sensor confirms your fence is live, on a schedule you set, and raises the bell the moment it isn’t.

What it does

Detects fence pulses — non-contact pickup (capacitive coupling to the fence wire), no high-voltage wiring into the device.
Reports state periodically — default interval is 5 minutes; configurable.
Reports immediately on state change — fence drops from active to inactive (or comes back), the device fires off a message right away rather than waiting for the next interval. This is the alert that matters.
Tracks pulse rate — a healthy charger has a known cadence. Drift from the expected rate (broken wire shorting to ground, low-battery charger) shows up before the fence dies completely.

Common failure modes it catches

Animal grounding — a sheep tangled in the wire pulls the fence voltage down. Pulses still happen but at much lower amplitude. Worth alerting.
Broken wire — fence is “on” at the charger but doesn’t reach the far end. Catch this by deploying multiple Electric Fence sensors at known points along the line.
Charger fault / dead battery — fence is silent. Most-common failure mode and the one that costs the most.
Vegetation grow-in — gradually loading the fence; the pulse-rate trend will show it before it fails.

Hardware

Battery-powered sensor with a non-contact pickup. The pickup is a small antenna held a few centimetres from the live wire — induced voltage from each fence pulse triggers a counter inside the device. No galvanic connection to the fence, so no risk of energiser pulses entering the electronics.

Monitoring and alerts

Mon, 01 Jan 0001 00:00:00 +0000

Sensors are only useful if someone notices the readings. OGLAS does both halves: a live picture of what’s happening right now, and an audible nudge when something needs your attention.

Real-time monitoring

The hub confirms every sensor message as it comes in, so you can see at a glance which sensors are healthy and which ones haven’t checked in.

Large display — a wall-mount dashboard that pages through every sensor on your network.
Small display — a desktop unit showing your two most important sensors at a glance.
Local dashboard — if you’d rather use a phone or laptop, Local exposes a full web UI on your own network.

All three read from the same on-device log. Nothing leaves your site.

Power Monitoring

Mon, 01 Jan 0001 00:00:00 +0000

Power Management reads your solar charge controller. Power Monitoring reads everything else — because plenty of off-grid power doesn’t come from a Victron MPPT.

What it does

Reads any source — mains feed, generator output, a battery bank via a shunt, or an individual circuit. AC or DC.
Measures voltage, current, and energy — instantaneous draw and accumulated kWh, per source or per circuit.
Finds the hogs — which load is quietly eating your battery overnight, and which circuit’s draw is creeping up.
Logs locally — every reading to your hub in open formats, no utility portal — see Your data is your data.

Hardware

Current transformers (AC) or a DC shunt feeding an OGLAS node, sized to the circuit. Multiple channels for a switchboard; a single channel for one load.

Satellite Hub

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS Satellite Hub is for the genuinely remote: a site with no mobile coverage, no fixed line, and no neighbour to bounce off. It collects sensor data on site like any other hub — and when you want that data off the site, it goes up over satellite rather than a telco.

When you want satellite

No coverage at all — back-country properties, offshore and coastal fishing, remote pump and bore sites, anywhere the phone says “no service”.
Off-site visibility from nowhere — you still want to glance at the site from your phone, even though the site itself has no terrestrial link.
Critical alerts that must get out — an out-of-water or equipment-fault alert that can’t wait for you to drive back into coverage.

What it does

Collects locally first — every reading still lands in on-site storage and feeds Local analysis, the same as any hub. Satellite is the exit, not a dependency for the system to work.
Sends a considered subset up — satellite airtime is precious, so the hub is configured to forward what matters: alerts, summaries, and the cadence of data you actually need remotely, rather than every raw sample.
Feeds Cloud — what goes up becomes your private off-site copy, viewable from a phone and shareable on your terms.

Trade-offs, honestly

Satellite is the most expensive transport per message and the most power-hungry, so it’s used deliberately: collect everything locally, send up only what earns the airtime. For sites that have any other path out — LTE, Wi-Fi, even HaLow — that’s usually the cheaper Cloud route. Satellite is the answer when there’s no other way.

Temperature

Mon, 01 Jan 0001 00:00:00 +0000

Not every temperature is the weather. The OGLAS Temperature sensor watches a specific point — and tells you the moment it leaves the range it’s supposed to be in.

What it does

Reads one or more probes — a single point or several on one node.
Alerts on thresholds — too warm, too cold, or out of a band, straight to the bell or your phone.
Logs the trend — so you can see the freezer creeping up for a day before it actually failed.

Where it goes

Freezer & cool room — the classic: catch a failure before the contents spoil.
Water tank & hot water — frozen-pipe risk at one end, legionella-safe storage at the other.
Kiln, oven, smoker — confirm a firing or curing schedule held.
Engine & bearing — an overheating bearing or engine as an early fault signal.
Glasshouse & shed — keep growing or stored goods in range.

Hardware

Thermistor, RTD, thermocouple, or a digital probe (DS18B20 and friends) to suit the range, on an OGLAS analog-class node. Mains or battery depending on the site.

Trap Trigger

Mon, 01 Jan 0001 00:00:00 +0000

Checking traps is the same problem as checking troughs: a long drive, mostly to find nothing. The OGLAS Trap Trigger sensor tells you the instant a trap fires, so you only make the trip when there’s a reason to — and you make it quickly.

What it does

Detects activation — a switch or sensor on the trap mechanism fires the moment it’s triggered.
Alerts immediately — straight to your hub, the bell, the cab display, or your phone via Cloud.
Time-stamps and locates — when it fired, and (with GPS) which trap, so you go straight to it.
Runs for months — it sleeps and waits for a single event, so battery life is measured in seasons.

Why it matters

For pest and feral control, a sprung trap left for days is both ineffective and inhumane. Knowing within minutes means you can dispatch or release quickly, and reset the trap so it’s working again sooner.

Water Pump

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS Water Pump controller starts and stops a pump on the conditions you set — a tank dropping, a trough low, solar surplus available — and, crucially, confirms the pump actually ran by measuring its current. It’s the Smart Switch tuned for the one job that matters most on a dry site.

What it does

Drives the pump on a rule — start when a tank or trough drops below a threshold; stop when it’s full. Combine with solar surplus so the pump runs when there’s sun to spare.
Confirms it ran — current sensing tells you the motor actually drew power, not that a relay merely clicked. “Pump on, no current” is a real failure you’ll hear about.
Dry-run protection — no flow or a current signature that says the pump is cavitating? Shut it down before it burns out.
Logs every cycle — run time, current, and starts-per-day to your hub, so a pump heading for failure shows up as a trend.

Pairs well with

Tank level and Water Trough — the level that drives the pump.
Water Flow & Pressure — confirms water is actually moving, not just that the motor spun.
Power Management — run on solar surplus instead of grid or generator.
Bell — a failed pump rings the homestead.

Building this into a larger site? That’s exactly what we do — start a custom build or email us.

Water Flow & Pressure

Mon, 01 Jan 0001 00:00:00 +0000

Level tells you how much water you have; flow and pressure tell you what it’s doing. The OGLAS Water Flow & Pressure sensor sits inline and watches the things that go wrong between the source and the tap.

What it does

Measures flow rate — litres per minute through a line, totalised over time so you know exactly how much moved.
Measures line pressure — at the pump or anywhere on the line.
Catches leaks — flow when nothing should be running is a burst pipe or a stuck valve, and it raises an alert straight away.
Catches blockages and a tiring pump — pressure climbing or falling outside its normal band points to a filter, a kink, or a pump losing its prime.

Hardware

An inline flow meter (pulse or analog) and a pressure transducer, read by an OGLAS node and reported to your hub. Runs from the same supply as a nearby pump, or battery + solar for a remote line.

Frost

Mon, 01 Jan 0001 00:00:00 +0000

A frost you find out about at dawn is a frost you’ve already worn. The OGLAS Frost sensor watches the conditions that lead to one and warns you — and your gear — in time to act.

What it does

Tracks air and ground temperature — at canopy and at ground level, where frost actually settles.
Reads dew point — temperature plus humidity tells you how close you are to forming frost, not just how cold it is.
Warns early — an alert as conditions approach the threshold, not once the damage is done.
Triggers protection — fire frost fans, an under-tree sprinkler, or a heater via a Smart Switch, automatically, at 2 am, without you standing in the cold.

Hardware

Paired temperature probes (air and ground) and a humidity sensor on an OGLAS node, sited in the block you’re protecting. Battery + solar — see Off-grid power.

Large display

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS large display is a hub with an LCD bolted on — the version you mount on a wall or in the office and walk past every morning to check the site at a glance.

What it shows

The screen is large enough to scroll through every sensor on your network without compromise:

Page 1 — gate state, latest bell trigger, last Vehicle Track arrival.
Page 2 — water troughs and tank levels with thresholds highlighted, plotted on a paddock map from the trough GPS coordinates.
Page 3 — electric-fence status across every monitored segment, with pulse-rate trend.
Page 4 — every analog node with its current reading, battery voltage, and time since last update.
Page 5 — Smart Switch state and current draw per switched load.
Page 6 onwards — power management (MPPT) data, weather, anything else you’ve wired in.

Pages cycle automatically, or you can pin one with the rotary encoder on the side.

Off-grid power

Mon, 01 Jan 0001 00:00:00 +0000

If your site runs on solar or batteries, every sensor’s power budget matters. OGLAS sensors are designed to spend most of their life asleep, and only the devices that need to listen continuously stay awake.

Battery sensors

The analog node and most “report a reading every minute” sensors:

Run on a single LiPo cell (3.7 V, 1000–2000 mAh is plenty).
Deep-sleep between samples — current draw drops to microamps.
Wake, read, send, wait for confirmation, sleep — the whole cycle is under a second of activity per minute.
Survive a full season on a charge for typical reporting intervals; longer with solar trickle.

We select hardware specifically for ultra-low deep-sleep current on battery-powered sensors. Slightly higher-power variants are available for always-on devices — pick the one that suits your install.

Air Quality

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS Air Quality sensor watches what’s in the air where people, animals, or plants are — and raises the alarm when a level climbs into a range that matters.

What it does

CO₂ — ventilation and comfort indoors; growth in a glasshouse; build-up in a confined space.
Methane (CH₄) — biogas, manure pits, and stores; this one also overlaps Safety (it’s combustible).
Particulates (PM2.5 / PM10) — dust, smoke haze, and air quality on fire-season days.
Temperature & humidity — the context every air reading needs.

Levels log to your hub with alerts on threshold, and can drive ventilation directly.

Small display

Mon, 01 Jan 0001 00:00:00 +0000

The OGLAS small display is a hub trimmed down to a desk-sized footprint — the handful of readings you actually look at every day, on a screen that stays out of the way the rest of the time. It comes in two sizes.

Tiny

The Tiny is about as small as a useful readout gets: a stick-sized OLED showing three values at a glance. The photo is a power example — battery 24.2 V, 122 W, 300 Wh — but the slots are configurable to whatever you check most:

Soil Moisture

Mon, 01 Jan 0001 00:00:00 +0000

Irrigating on a timer waters the calendar, not the crop. The OGLAS Soil Moisture sensor reads what the ground actually holds — at root depth — so water goes on when it’s needed and stays off when it isn’t.

What it does

Reads soil moisture — volumetric water content from a probe in the root zone; one or several depths.
Reads soil temperature — the other half of the germination and growth picture.
Reports on a schedule — hourly is plenty; deep-sleep between reads keeps it running a season on battery.
Drives irrigation — feed the reading to a Smart Switch: water only when moisture is below threshold and the weather isn’t about to do it for you.

Hardware

A capacitive soil probe (no corroding exposed electrodes) on an OGLAS analog node, battery-powered with a small solar trickle — see Off-grid power.

Water Quality

Mon, 01 Jan 0001 00:00:00 +0000

Plenty of water is no good if it’s the wrong water. The OGLAS Water Quality sensor monitors the condition of what’s in your tanks, troughs, dams, and tanks for stock, irrigation, or aquaculture.

What it does

pH — drift outside the safe band for stock, crops, or fish.
Salinity / EC / TDS — dissolved solids creeping up in a bore or dam.
Temperature — drives dissolved-oxygen levels in aquaculture and dam health generally.
Turbidity — cloudiness from algae, runoff, or a disturbed dam.
Dissolved oxygen (option) — the one that matters most for fish.

Readings go to your hub on a schedule, with alerts when any value leaves its safe range.
