Principle Introduction:

The sensing material of MIX1004B is tin dioxide SnO2, which has low conductivity in clean air. When the combustible 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.

MIX1004B has high sensitivity to methane, propane butane etc. combustible gas. The sensor can work in high temperature. It is low cost sensor and can be used in different applications.

Feature:

* High sensitivity to wide range of combustible gas

* High sensitivity to methane

* Long life and low cost

* High ant seismic

Application:

* Domestic gas leakage detectors

* Portable gas detectors
