Reading electrochemical events in water that is electrically noisy can be a bit tricky. Pumps, heaters, chillers even overhead lights can leak electrical noise into a seemingly closed system. When using a hand held device, such as a pH meter it is automatically immune from electrical noise, this is because its battery powered and does not share a common ground with the rest of your system.
To stop electrical noise you will need to supply your circuitry with isolated power and data lines. The Atlas Scientific PWR-ISO is a simple 8 pin module that will eliminate electrical noise in your sensor application.
- Sources up to 150ma of fully isolated power
- Will work with UART or I2C protocols
- Only 32ma current draw in quiescent mode
