Smart Electronics MQ8 MQ 8 MQ-8 Smoke Liquefied Flammable Methane Gas Sensor Module for Arduino Diy Starter Kit
Product Overview:
Sensitive material MQ-8 gas sensors used in clean air, low
conductivity tin oxide (SnO2). When there is an environment in
which the combustible gas sensor, conductivity sensor with
increasing concentration of combustible gases in air increases. Use
simple circuit can convert the change in conductivity of the gas
concentration corresponding to the output signal. MQ-8 hydrogen gas
sensor of high sensitivity monitoring of other hydrogen-containing
gas is also very good. The sensor can detect a variety of
hydrogen-containing gas, in particular, city gas, is a low-cost
sensor suitable for a variety of applications.
Application:
Application:
Suitable for home or industrial hydrogen leak monitoring devices.
Can not interfere with ethanol vapor, soot, carbon monoxide and
other gases.
Features:
Using high-quality dual-panel design,with power indicator and TTL
signal output instructions.
The switching signal having a DO (TTL) output and analog output AO.
TTL output valid signal is low. ( Low-level signal when the output
light can be directly connected to the microcontroller or relay
module )
Analog output voltage with the higher concentration of higher
voltage
There are four screw holes for easy positioning.
Has a long life and reliable stability
Rapid response and recovery characteristic
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 .

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
