MQ-8 Hydrogen Sensor module

MQ-8 Hydrogen Sensor.  H2 gas sensor, with 80% market share in the gas sensor field. The sensitive material of MQ-8 gas sensor is SnO2, which has 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 to the output signal of gas concentration through a simple circuit. MQ-8 gas sensors have high sensitivity to hydrogen gas, and also have 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.
Detection Gas: Hydrogen, H2 sensor
Detection Range: 100～1000ppm(H2)
Application: Domestic gas leakage alarm
