Principle Introduction:

The sensing material of MIX1007B is tin dioxide SnO2, which has low conductivity in clean air. When the  Carbon Monoxide(CO)  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.

MIX1007B  Carbon Monoxide(CO) Gas Sensor has high sensitivity to carbon monoxide. The sensor can work in high temperature. It is low cost sensor and can be used in different applications.


High sensitivity to wide range of carbon monoxide
High sensitivity
Long life and low cost
High anti-seismic


Domestic gas leakage detectors
Portable gas detectors
