MQ-9 MQ9 Carbon monoxide alarm combustible gas sensor module

Product Overview:
Sensitive material MQ-9 gas sensors used in clean air, low conductivity tin oxide (SnO2). High-low temperature cycling detection mode (1.5V heating) detecting carbon monoxide sensor's conductivity increases with the air of carbon monoxide gas concentration increases, spurious adsorption at high temperature (5.0V heat) detection of combustible gases methane, propane, and cryogenic cleaning gas. Using a simple circuit to change the conductivity, concentration of the gas is converted to the corresponding output signal. MQ-9 gas sensor for high carbon monoxide, methane, liquefied petroleum gas sensitivity, this sensor can detect a variety of carbon monoxide and combustible gas, is a low-cost sensor suitable for a variety of applications.

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
