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 detecting of Hydrogen.  Due to its high sensitivity and response time, measurements can be taken as soon as possible. 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.


1. Main chip: the LM393, MQ-8 gas sensor
2. Working voltage: DC5V
3. With a signal output instructions.
4. Dual signal output (TTL level output and analog output)
5. TTL output valid signal for low level. (when the low output electric signal lights at 4. ordinary times, can be directly pick up SCM)
6. Analog 0 ~ 5 v voltage, the higher the concentration, the higher the voltage.
7. High sensitivity to hydrogen
8. Can be resistant to ethanol steam, LPG (petroleum), smoke interference
9. Has a long service life and reliable stability
10. Quick response recovery features
