Principle Introduction

The sensing material of MEWOI-MIX1004 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.
MIX1004 Combustible (CH4) Gas Sensor 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.


* High sensitivity to wide range of combustible gas
