Principle Introduction:
The sensing material of MIX1002B is tin dioxide SnO2, which has low conductivity in clean air. When the combustible or smoke 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.
MIX1002B Combustible and Smoke 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 to Combustible gas
Fast response and recovery
Good seismic performance
Low power consumption
Long life and low cost
Application:
Household gas leakage alarm
Portable smoke gas detector
Smoke and gas alarm
