Use any Ion Specific Electrode, pH, ORP, or mV Probe
- Measure pH with temperature compensation
- Measure ORP and Eh
- Raw mV
- Temperature in Celsius/Fahrenheit
- Library can be easily extended for any probe
- Electrically Isolated
What it is
An I2C sensor that can read a pH probe. Attach a waterproof temperature sensor for temperature compensation with the attached connector. The firmware on the device provides two calibration options, single or dual point.
All boards have a conformal coating to help protect against moisture, corrosion, and short circuits.
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.
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.

Don't forget to add a Qwiic wire to your order. 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.
Knowing the temperature isn’t really required for an accurate measurement, but it’s useful to know and you can easily connect a waterproof temperature probe to the board.
