Raspberry Pi HAT · Open Firmware

Anytime. Anywhere.
Know your water.

Six sensor channels, LoRaWAN telemetry, and an on-board relay — continuous readings from any tank, pond, or treatment system, shipped from Austin.

The Device

One board. Six probes.

A Raspberry Pi HAT that reads six channels of water chemistry, holds them in an on-board buffer when the link drops, and ships them out over LoRa. When a reading crosses a line you set, the same board trips a relay — a pump, a valve, an aerator. Hover or focus any pin to see what it is.Tap any badge to see what it is.

What It Watches

Six channels. Plus a digital bus.

Six core parameters read every 60 seconds — and an RS485 expansion bus for digital probes like chlorine and EC/salinity. Here’s what each one tells you.

A0 · BNC

pH

Acid or base — drifts before the fish do.

A1 · BNC

TDS

Dissolved salts, climbing or holding steady.

A2 · Analog

Turbidity

Cloudiness — the first sign of a bloom.

A3 · BNC

ORP

Whether your disinfection is working.

GPIO · 1-Wire

Temperature

The reference everything else leans on.

UART · NMEA

GPS

Geo-stamps every batch of readings.

RS485 · Modbus digital bus · optional probes
RS485 · Modbus

Chlorine

Residual disinfectant, 0–20 mg/L — optional digital probe.

RS485 · Modbus

EC / Salinity

Conductivity and salt content — optional 5-in-1 digital probe.

System Overview

One system. Any water.

From probe to dashboard: the WQM-1 reads, buffers, and transmits to BlueSignal Cloud; thresholds fire alerts and the relay closes the loop. Swipe through where it runs — the same readings power the WaterQuality.Trading network.

Residential

Residential

Well water and rainwater harvesting. A text the moment pH drifts or TDS spikes, before it reaches the tap.

Ponds & Spas

Ponds, Pools & Spas

Chlorine and pH watched around the clock — pools, spas, koi ponds, and display tanks. The relay drives the doser; the dashboard texts you before anyone notices.

AWG

Atmospheric Water Generation

Condensate quality checked before it ever reaches the tank — pH, TDS, and chlorine on every batch the machine pulls from the air.

Also deployed for — commercial
Nutrient Banking

Treatment-cell readings that mint credits on WaterQuality.Trading.

Stormwater

Retention-basin monitoring, GPS-tagged for MS4 compliance.

Algae Control

Turbidity and ORP trends caught days before a bloom shows.

Aquaculture

Dissolved-oxygen alarms wired to the aerator before dawn.

Storage

Offline-First SQLite Buffer

WAL-mode database holds readings locally when the link drops. Syncs automatically once the LoRa link returns.

Radio

LoRaWAN Class A

SX1262 transceiver, 15 km line-of-sight. Cayenne LPP payloads, AES-128 encrypted.

Control

Relay Output

10 A relay for pumps, valves, and dosing systems. Fires on a threshold rule or a cloud command.

Expansion

I²C Expansion Bus

Exposed I²C header for more probes — barometric pressure, dissolved oxygen, or custom sensors.

Every connector, voltage, protocol, and tolerance is on the datasheet — compute, radio, power, and I/O in full.
