||Part # EZO-ORP
Connect your ORP probe to this circuit to create a workable signal for your microprocessor using UART or I2C protocol.
Works with any brand and type of ORP sensor.
ORP stands for oxidation/reduction potential. Oxidation is the loss of electrons and reduction is the gain of electrons. The output of the probe is represented in millivolts and can be positive or negative.
Just like a pH probe measures hydrogen ion activity in a liquid; an ORP probe measures electron activity in a liquid. The ORP readings represents how strongly electrons are transferred to or from substances in a liquid. Keeping in mind that the readings do not indicate the amount of electrons available for transfer.
