Principle Introduction:

The sensing material of MIX1017 is tin dioxide SnO2, which has low conductivity in clean air. When the Ammonia gas exists, the conductivity of the sensor will be raise according to the gas concentration goes up. Through a simple circuit, to convert the changes of conductivity to correspond to the gas concentration.

MIX1017 Ammonia(NH3) Gas Sensor has high sensitivity to ammonia. The sensor can work in high temperature. It is low cost sensor and can be used in different applications.


High sensitivity

Low power consumption

Long life and low cost

Fast response and recovery


Domestic Ammonia gas leakage detectors

Portable Ammonia gas detectors
