MQ-9B Dual Gas CO And CH4 Detection Sensors Industrial use
The sensitive material of MQ-9B gas sensor is SnO2, which has low conductivity in clean air. It detects carbon monoxide (1.5V) by cycling high and low temperatures. At high temperature (5.0V), it can detect CO and remove other gases adsorbed at low temperatures. As the concentration of CO and CH4 gases increases, the conductivity of the sensor increases. Users can convert the change in conductivity into the corresponding gas concentration output signal through a simple circuit.
Application:
Widely used in household CO gas leak alarms, industrial CO gas alarms and portable CO gas detectors.
