MQ-136 MQ136 Hydrogen Sulfide Gas Sensor Module H2S Gas Sensor Detector
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: analog level signal
TTL output high and low level. (Can be directly connected to microcontroller or relay module)
Special reminder: after the sensor is energized, it needs to be warmed up for about 20S for the measured data to be stable, and it is normal for the sensor to be hot because there is an electric heating wire inside, and it is not normal if it is hot.
