MQ-2 MQ-3 MQ-4 MQ-5 MQ-6 MQ-7 MQ-8 MQ-9 MQ-135 Detection Smoke methane liquefied Gas Sensor Module
Features:
Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
Special note: After the sensor is powered,needs to warm up around 20S,measured data was stable,heat sensor is a normal phenomenon,because the internal heating wire,if hot is not normal .
Application:
Suitable for home or industrial hydrogen leak monitoring devices. Can not interfere with ethanol vapor, soot, carbon monoxide and other gases.
Wiring:
VCC: positive power supply (5V)
GND: power supply is negative
DO: TTL switching signal output
AO: analog signal output
NOTE:
After the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is normal
