Principle Introduction:
The sensing material of MIX1005 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.
MIX1005 Combustible (CH4 & LPG) Gas Sensor has high sensitivity to LPG (C3H8) 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 LPG/CH4 gas
* Stable performance
* Long life and low cost
* Good seismic performance
* Strong anti-interference ability
Application:
* Gas leakage detector and alarm for civil use
* Portable gas detector
