Principle Introduction:
The sensing material of MIX1024 is tin dioxide SnO2, which has low conductivity in clean air. When the combustible methane 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.
MIX1024 Combustible Methane/CH4 Gas Sensor has high sensitivity to 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
simple application circuit
low power consumption
long life
strong anti-interference capability
Application:
* Civil gas leakage detector and alarm
* Portable gas detector
