1. Introduction
Grove-Gas Sensor (O₂) is a kind of sensor to test the oxygen concentration in air, which is based on the
principle of the electrochemical cell to the original work. You can know clearly the current oxygen
concentration when you output voltage values proportional to the concentration of oxygen and refer to the
oxygen concentration linear characteristic graph. It’s very suitable for detecting oxygen concentration in the
environment protection. Grove - Gas Sensor(O₂) is an organic reaction module, it can provide a little current
while putting it in the air, we don't need to provide an external power to it, and output voltage will change
as time current changes.
