MQ-9B MOS Sensor for Carbon Monoxide CO Gas

Profile :

’Sensitive material of MQ-9B gas sensor is SnO2, which with lower conductivity in clean air. It detects carbon monoxide (1.5V) by method of cycle high and low temperature. At high temperature (5.0V), it can detect CO as well as clean the other gases adsorbed at low temperature. The sensor’s conductivity gets higher along with the CO and CH4 gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.

Features:

It has good sensitivity to carbon monoxide and methane in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.

Main Applications:

It is widely used in domestic CO gas leakage alarm, industrial CO gas alarm and portable CO gas detector.
