The Grove-Gas Sensor (O₂) tests the oxygen concentration in air, based on the principle of the electrochemical cells. It’s suitable for detecting oxygen concentration within the environment.
Note:The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires more precise and costly instruments and cannot be achieved with a single gas sensor.
