                                                              MQ-8 Hydrogen H2 Gas Sensor

 

Profile :

Sensitive material of MQ-8 gas sensor is SnO2,which with lower conductivity in clean air. When hydrogen gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ-8 gas sensor has high sensitivity to hydrogen gas, also has anti-interference to other gases. This sensor can detect hydrogen, especially city gas. It is a kind of low-cost sensor for kinds of applications.

 

Features :

It has good sensitivity to hydrogen gas 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 gas leakage alarm, industrial flammable gas alarm and portable gas detector.
