Problems a level sensor can’t see

The annual lab test and the strip test tell you what the water was.Not what it is.

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. Turbidity and TDS move days before the water clouds.

04

Manual checks lie.

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

The Device

One board.Four probes.

A single open-firmware mainboard reads pH, TDS, turbidity and temperature — every 60 seconds, in lakes, ponds, wells and treatment systems. ORP, chlorine and conductivity ride the RS485 bus as optional probes.

What It Watches

Four base channels.Plus a digital bus.

pH, TDS, turbidity and temperature read every 60 seconds, geo-stamped by GPS. The RS485 bus takes optional digital probes — ORP, chlorine, EC/salinity. Here’s what each one tells you.

A2 · BNC

pH

Acid or base — drifts before the fish do.

Range
0 – 14 pH
Probe
Industrial BNC electrode
A0 · JST-XH

TDS

Dissolved salts, climbing or holding steady.

Range
0 – 1000 ppm

Conductivity, dual-mode
A1 · JST-XH

Turbidity

Cloudiness — the first sign of a bloom.

Range
0 – 3000 NTU
Method
IR scatter, 850 nm

Temperature

The reference everything else leans on.

From the pond to your pocket.

The unit keeps every reading on its own storage first, so a dropped connection loses nothing. When the link is back, the backlog follows in order.

01

The probes read.

Four 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 reading leaves the site.

Stored on the unit first, then sent to BlueSignal Cloud over the site’s Wi-Fi. A 915 MHz radio is on the board for sites without a connection; that network path ships when it is live, not before.

Wi-Fi · store-and-forward
03

You get the alert.

The cloud stores it, charts it, and notifies you when a reading crosses a threshold you set. The same threshold can switch site equipment through the four relay outputs and installer-supplied gear.

System Overview

It doesn’t just alert.It switches.

A threshold fires an alert — and four relay outputs switch site equipment, such as water generators, through installer-supplied gear. 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 dashboard texts you before anyone notices, and a relay output signals installer-supplied gear.

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. 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, a relay output signals installer-supplied gear, and the record is there for the MS4 report.
