Principle Introduction:
The sensing material of MIX1007B is tin dioxide SnO2, which has low conductivity in clean air. When the Carbon Monoxide(CO) 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.
MIX1007B Carbon Monoxide(CO) Gas Sensor has high sensitivity to carbon monoxide. The CO gas sensor can work in high temperature. It is low cost sensor and can be used in different applications.
Feature:
Long life and low cost
High anti-seismic
Small volume
Low power consumption
Good consistency
Good sensitivity to carbon monoxide gas
Application:
Domestic gas leakage detectors/alarms
Portable gas leakage detectors/alarms
