Isolated EC Probe Interface Sensor

The board uses the Qwiic Connect System, an easy-to-use, polarized, push-to-fit connector. No more mistaken connections or soldering header pins. Adafruit calls these connectors STEMMA QT.

All boards have a conformal coating to help protect against moisture, corrosion, and short circuits.

Self Isolation

When different probes are connected to the same controlling device, they can cause interference. The environment also causes interference due to ground-loops or other electrical noise like pumps. Electrically isolating the probe can help to prevent these problems.

Using it

There is documentation on the specification, setup, and use of the sensor.

The Arduino IDE, PlatformIO, and Particle.io library is in their respective library managers. Any Arduino compatible board will work.

A python library is available for the Raspberry Pi.

Embedding it

The board has castellated headers, so you can embed it permanently into your project.

Buying it

The sensor comes with one Qwiic wire, you can buy extras if needed. There are 3 types of wires to choose from; Qwiic to Qwiic used to connect a Qwiic board to another Qwiic board, Qwiic to male headers, and Qwiic to female headers.

It also comes with a dust cap, hex nut, washer and rubber seal for the BNC connector.

For accurate measurements, you need to be able to provide the water`s temperature. So you`ll probably want to get a waterproof temperature sensor, it connects directly to the board. But the library will accept the temperature from any source.
