The Unit

AQL-1 Field Sensor

One sealed block of machined intent. Clamp it, bolt it, or drop it magnet-first onto steel — then walk away.

  • ▣
    Sleeps deep, wakes fastMicro-amp idle discipline. The unit rests dormant almost all of its life and wakes only when there is work — or the moment you call it.
  • ▣
    Answers when calledOn-demand interrogation from base. Ask, and it measures and reports in seconds — then goes dark again.
  • ▣
    Self-healing linkProprietary link negotiation finds the fastest reliable channel and falls back to maximum range on its own. No hand-tuning, ever.
  • ▣
    Sensor-agnostic coreLevel, soil, gates, tamper, temperature — the same hardened core runs them all.
  • ▣
    Enclosure to suit the missionHousings vary by sensor and posting — matchbox-sized or similar, sealed to the job, with an optional small solar panel for indefinite endurance. Units shown are representative.

Capability

Built like field kit,
because it is field kit

CAP 01

Off-grid by design

Runs where phones don't. The radio link doesn't care about towers, load-shedding or dead zones — it carries your data across the farm on its own.

CAP 02

Years, not weeks

Aggressive power engineering measured at the micro-amp level. A single small cell holds the line for years of duty.

CAP 03

Command from base

Pull a reading on demand, schedule reports, or re-task the radio — all from the base station. The unit obeys and returns to blackout.

CAP 04

Recovers itself

Lose contact for any reason and both ends hunt for each other on a disciplined fallback ladder until the link stands again. No ladder climbing, no site visits.

CAP 05

Tethered mode

Plug any unit into a laptop and it becomes a live high-speed instrument for commissioning and QA — then unplug and redeploy.

CAP 06

Fleet-ready

One base station shepherds a fleet of units across the property — tanks, troughs, gates and fence lines on one screen.

CAP 07

Radar sensing head

A radar head watches the ground at the post — presence, approach and direction, telling a vehicle from a person. It sees metres, where it matters; the radio carries the word home across kilometres.

CAP 08

It learns the station

Readings are interpreted, not just logged. Our detection layer learns what normal looks like for each station — this tank, this gate, this season — so you are told when something is genuinely wrong instead of every time a number moves.

Deployment

Water. Farm. Perimeter.

Same unit. Different war.

OP · BENCH

Radio & Bench Proving

Nothing goes onto a fence post that has not been across the bench first. Every unit is checked on a spectrum analyser, its current draw profiled at micro-amp resolution, and its link run under load before sign-off. Thirty years of instrumentation engineering behind the design — not a first attempt at hardware.

◫MINUTES

Deploy

Magnet it to steel, bolt it to a post, strap it to a pipe. Boots on, unit on, walk away — no wiring, no laptop, no settings to get wrong in the sun.

Link

The base station hunts it down, proves the channel and locks on by itself. No aiming, no climbing, no coaxing a signal out of a hill.

FINDPROVELOCK
◉FROM ANYWHERE

Command

Levels on screen, readings on demand, a shout when something moves. From the stoep, the bakkie or the office — the farm reports to you.

WATCHPULLALERT
Comms & Power

Every link. Every power source.

Four ways in, three ways to feed it. Whatever the posting demands.

LINK 01

LoRa Long-Range

Sub-GHz, licence-free. 2–10 km line-of-sight, terrain dependent — clean across a working farm without a single tower.

LINK 02

Bluetooth

Walk up and commission from a phone. No cables, no laptop in the field — pair, calibrate, walk away.

LINK 03

USB Tethered

Plug any node into a laptop and it becomes a live high-speed instrument. The base station runs the fleet over the same port.

PWR 01

Battery — Years

Micro-amp sleep discipline on a single small cell. Multi-year endurance, calculated from draw measured on a bench power profiler. Every micro-amp in that sum came off our own meter — the duty cycle is measured, the years are arithmetic, and we will show you both.

PWR 02

Solar Assist

Optional small panel turns years into indefinite. A palm-sized cell is all the African sun needs.

PWR 03

Modes

On-demand interrogation · scheduled self-report · tethered instrument. Switch any node's doctrine from the base, over the air.

LINK 04

GPS Position

Optional position tag — every node knows exactly where it stands, and your map shows it. Move it, and the grid follows.

Area Mesh

Your whole property. One mesh.

Every node on station, every path alive. Nodes relay for their neighbours — lose one route and the mesh finds another.

Every unit comes with a free account on the UAC portal. Register, add your base station and run the whole fleet from any browser — levels, gates, alerts and history. No monthly fee, no tier, no seat count. It stays free for as long as you own the hardware.

  • Free — account, portal and fleet view
  • Free — alerts, history and export
  • Optional — AI interpretation, paid only if you switch it on

The hardware works whether the portal is on or off. Nothing you have paid for stops working if you never log in.

Field Doctrine
STANDING ORDER 01African ruggedness

Heat. Dust. Distance. Lightning. Load-shedding. That list was the design brief from the first sketch — designed and built here, by the engineer who has to answer for it, not designed for Europe and shipped south with a new label. SA field trials are open now.

STANDING ORDER 02Measured, not promised

Every endurance figure starts as draw measured on a bench power profiler. The micro-amps are measured and logged; the years are arithmetic off those numbers — and we will show you the working. We do not quote what we have not seen on the meter.

STANDING ORDER 03Yours, outright

Your data lands on your property, on your base station, on your screen. No forced cloud, no monthly ransom, no vendor holding your farm hostage — and anything that leaves your property is your choice, switched on by you.

Field trials now open

Put one on your tank.

Tell us about your property and what you need watched. We'll spec a deployment and put hardware in your hands.
