MQ-8 Hydrogen Gas Sensor Module

The MQ-8 Hydrogen Gas Sensor Module can detect Hydrogen gas in the surrounding air. The concentration of the gas is output as an analogue voltage reading. This sensor can detect concentrations between 100-1000ppm and is suitable for portable gas detectors and home safety automation systems.

The module requires two (2) different voltage inputs to operate. Heater voltage should be 5V (AC or DC) and Loop Voltage should be less than 24VDC.

Please read the MQ8 datasheet for more info about the sensor.
