Introduction

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.
