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.
“Pond turned over near 04:00. DO sagged 8 min, aerator caught it. Watching turbidity through noon.”
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.
Six channels.
Six parameters, read every six minutes. Here’s what each one tells you.
pH
Acid or base — drifts before the fish do.
TDS
Dissolved salts, climbing or holding steady.
Turbidity
Cloudiness — the first sign of a bloom.
ORP
Whether your disinfection is working.
Temperature
The reference everything else leans on.
GPS
Geo-stamps every batch of readings.
How it all connects.
From probe to dashboard. The WQM-1 reads, buffers, and transmits over LoRaWAN to BlueSignal Cloud; thresholds fire alerts and the relay closes the loop. The same readings power the WaterQuality.Trading network.
Offline-First SQLite Buffer
WAL-mode database holds readings locally when the link drops. Syncs automatically once the LoRa link returns.
LoRaWAN Class A
SX1262 transceiver, 15 km line-of-sight. Cayenne LPP payloads, AES-128 encrypted.
Relay Output
10 A relay for pumps, valves, and dosing systems. Fires on a threshold rule or a cloud command.
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.
Read the full datasheetWhere it’s already running.
Aquaculture
Dissolved oxygen crashes before dawn. Wire the relay to your aerator and it kicks on at the threshold, before the fish notice.
Algae Control
Turbidity and ORP climb days before a bloom shows. Catch the trend, trip an ultrasonic transducer, skip the manual dosing.
Stormwater
Retention-basin readings, GPS-tagged and logged for MS4 compliance — already in the format the report wants.
Residential
Well water and rainwater harvesting. A text the moment pH drifts or TDS spikes, before it reaches the tap.
Priced for who’s watching.
