Product Details


The MQ8 Gas Sensor module is useful for gas leakage detection. They are used in gas leakage detecting equipments in home and industry, are suitable for the detection of Hydrogen.  Due to its high sensitivity and response time, measurements can be taken as soon as possible. The Hydrogen sensor (MQ8) is capable of detecting Hydrogen gas in air. It can be installed in industries where hydrogen is used widely. It’s range of sensing varies from 100 to 10000 ppm of Hydrogen gas in air. This sensor has selective digital or analog output capability which can be measured easily with SPDuino or any other micro controller.

When hydrogen gas exists, the sensor’s conductivity gets higher along with the gas concentration. Users can convert the change of conductivity to corresponding output signal of gas concentration through a simple circuit.Try and avoid alcohol, LPG, cooking fumes as the sensor has slight sensitivity to these substances and this may affect results. The sensitivity of the sensor can be adjusted by using the potentiometer.


  •          Selective digital/analog output
  •          High sensitivity to hydrogen gas
  •          Small sensitivity to alcohol, LPG, cooking fumes
  •          Stable and long life


  •          Direct and easy interface
  •          High sensitivity and response time
  •          Anti-interference to other gases
  •          Easy to interface with any controller


  •          They are used in gas leakage detecting equipment in family and industry, are suitable for detecting of Hydrogen (H2), avoid the noise of alcohol and cooking fumes, LPG,CO.
  •          It is widely used in domestic gas leakage alarm, and portable gas detector.
