The MQ-8 gas sensors used in gas-sensing material is tin oxide (SnO2), low conductivity in clean air. When the hydrogen gas present in the sensor surroundings, the sensor’s conductivity increases with the air of combustible gas concentrations increase with increasing. Using a simple circuit to the conductivity change is converted to output signals corresponding to the concentration of the gas.
MQ-8 gas sensors for hydrogen sensitivity monitoring of hydrogen gas is also very good. This sensor can detect a variety of hydrogen gas, city gas, is a low-cost sensors for a variety of applications.
1. High sensitivity to Hydrogen gas
2. Long life and low cost
3. Simple drive circuit
1. Domestic gas leakage detector
2. Industrial Hydrogen detector
3. Portable gas detector
