Q & A

MQ-8 Hydrogen Gas Sensor Module: the sensitive material used for clean-air conductivity is lower-tin dioxide (SnO2). When the sensor is in an environment with combustible gases, its conductivity increases as the concentration of those gases in the air increases.

Specifications:

Working voltage: 5V DC
Chip: LM393, ZYMQ-8 Hydrogen Gas
Interface: Analogue
Pin definition:
GND – Power supply
Vcc – Power supply
DO – Digital output
AO – Analog output
Dual signal output: (Analogue output and TTL level output)
Gas Detection: Hydrogen Gas
Detection of Concentration:100-1000ppm
Power consumption (current): 150mA
DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively non-polluting), the highest concentration voltage is about 4V
Fast response and high sensitivity
