Although it is a common measurement, accurately reading pH is very difficult. Atlas Scientific’s EZO-pH circuit gives engineers the ability to read pH with the same accuracy and capabilities that were traditionally only found in expensive bench-top meters.

With an easy-to-use data protocol, simple command structure, and an easy-to-read datasheet engineers of any skill level will be able to add high-accuracy pH readings to their next project quickly.

Connect your pH probe to this circuit to create a workable signal for your microprocessor using UART or I2C protocol.
Works with any brand and type of pH sensor.
