2、 Function Description
The gas sensing material used in the ammonia gas sensor is Tin(IV) oxide (SnO2) with low conductivity in clean air. When there is ammonia in the environment where the sensor is located, the conductivity of the sensor increases with the increase of ammonia concentration in the air. Using a simple circuit, the change in conductivity can be converted into an output signal corresponding to the gas concentration. It can detect various ammonia containing gases and is a low-cost sensor suitable for various applications.
