Do you know your water?
We’ll tell you what’s in it.

Sensors, smart buoys, and algae control for lakes, ponds, and wells. pH, TDS, turbidity, ORP — six parameters, real time. Built in Austin, TX.

Problems a level sensor can’t see

Most water problems are silent until they aren’t.

A bad well doesn’t announce itself. A pond turns over at 4am. The softener fails on a Tuesday. You find out after the fish, the plants, the filter.

01

Wells drift.

pH and TDS move for weeks before a monthly test catches it.

02

Ponds crash.

Oxygen sags before dawn; the fish go before you know.

03

Tanks rot.

Cisterns grow biofilm quietly. ORP shows it days ahead of cloudy water.

04

Manual checks lie.

A strip test once a month misses what happens at 3am.

The Device

One board. Six probes.

A single open-firmware mainboard reads pH, TDS, turbidity, ORP and temperature — every 60 seconds, in lakes, ponds, wells and treatment systems.

What It Watches

Six channels. Plus a digital bus.

Six quality parameters read every 60 seconds. The RS485 bus and a spare ADC channel take optional probes — chlorine, EC/salinity, or a level transducer if you want quantity too. Here’s what each one tells you.

A0 · BNC

pH

Acid or base — drifts before the fish do.

Range
0 – 14 pH
Accuracy
±0.02 pH
A1 · BNC

TDS

Dissolved salts, climbing or holding steady.

Range
0 – 1000 ppm
Accuracy
±2% FS
A2 · Analog

Turbidity

Cloudiness — the first sign of a bloom.

Range
0 – 3000 NTU
Method
IR scatter, 850 nm
A3 · BNC

ORP

Whether your disinfection is working.

Range
±2000 mV
Accuracy
±5 mV
GPIO · 1-Wire

Temperature

The reference everything else leans on.

Range
−5 – 85 °C
Accuracy
±0.5 °C
UART · NMEA

GPS

Geo-stamps every batch of readings.

Accuracy

Probe · cloud · phone

From the pond to your pocket.

No Wi-Fi needed at the site. The box talks to a LoRaWAN gateway up to ~15 km away line-of-sight, and the gateway is the only thing that needs an internet connection.

01

The probes read.

Six channels sampled every 60 seconds. Raw analog from the probes, converted on-board and stored before anything is transmitted.

WQM-1 · on-site
02

The packet flies.

AES-128 encrypted, Cayenne LPP payload, out over 915 MHz to the nearest LoRaWAN gateway — up to 15 km line-of-sight.

915 MHz · SX1262
03

You get the alert.

The cloud stores it, charts it, and notifies you when a reading crosses a threshold you set. The same data drives the relay.

System Overview

It doesn’t just alert. It acts.

A threshold fires an alert — and the 10 A relay closes the loop: dosing, aeration, algae control. Swipe through where it runs.

Residential

Residential

A well shifts with the aquifer and nobody tests it for months. pH and TDS read every 60 seconds — you get a text the moment either moves.

Ponds & Spas

Ponds, Pools & Spas

pH drifts overnight and the sanitizer stops working — that is how a pool goes green. The relay drives the doser; the dashboard texts you before anyone notices.

AWG

Atmospheric Water Generation

Condensate picks up whatever the air and the machine give it. pH, TDS and temperature read on every batch before it goes to storage.

Aquaculture

Aquaculture

Temperature, pH and turbidity in every raceway, every 60 seconds, with the relay on the aerator. Lose one tank of fish and the unit has paid for itself.

Stormwater

Stormwater & Algae Control

A retention pond turns green in a week of heat. Turbidity and pH trend before the bloom, the relay runs the aerator or the doser, and the record is there for the MS4 report.
