DF Robot Electrochemical Oxygen / O2 Sensor (0-100%Vol, I2C)
The Gravity Electrochemical Oxygen (O2) Sensor measures oxygen levels from 0-100%Vol with I2C digital output, ideal for applications like O2 generators and exhaust detection. It features a factory-calibrated AO2 CiTiceL® probe, offering high stability, sensitivity, and a two-year lifespan. Designed for easy integration with controllers like Arduino, ESP32, and Raspberry Pi, it includes built-in calibration algorithms for accurate readings. The sensor’s strong anti-interference capability and compatibility with Gravity interfaces make it quick to deploy in various projects. Avoid exposure to high concentrations of solvent vapors during use and storage.
