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