Winsen MQ-8 Hydrogen Sensor is an original and brand new H2 Detection Sensor. With a long lifespan and low price, for detecting hydrogen, especially city gas.

The sensitive material of the 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 a 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.


  1. Responsive to Hydrogen (H2) gas
  2. Compatible with 5V
  3. Cost-efficient
