Gravity: Electrochemical Oxygen / O2 Sensor (0-100%Vol, I2C)

This full-scale oxygen / O2 sensor employs the original AO2 CiTiceL® oxygen sensor probe and features a measurement range of 0-100%Vol and I2C digital output , which can be adapted to application scenarios including oxygen / O2 generators, automobile exhaust, and air-fuel ratio detection.

The DFRobot oxygen / O2 sensor has a built-in calibration algorithm on the signal board that can quickly perform single-point or double-point calibration so as to accurately measure the oxygen / O2 concentration in the environment. Based on the principle of electrochemistry, the sensor probe comes with strong anti-interference ability, high stability and sensitivity, and up to two years of service life. It is compatible with mainstream controllers such as Arduino , ESP32 , Raspberry Pi , etc. Besides, the sensor is designed with an easy-to-use Gravity interface, and with our sample codes, you can quickly build an oxygen / O2 detector.

Caution: Exposure to high concentrations of solvent vapors is avoided, both during storage, fitting into instruments, and operation.
