MQ-6 Sensor Description:
Sensitive material MQ-6 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-6 gas sensor for pane, butane, LPG high sensitivity, natural gas and has a good sensitivity. The sensor can detect a variety of combustible gas, it is a low-cost sensor suitable for a variety of applications.


Module Applications:
Suitable for home or industrial on LPG?Liquefied petroleum gas?, Butane, pane, LNG?liquified natural gas?Detection means. Excellent resistance to ethanol vapor, mist interference.
Module Features:
1, using dual-panel design, with power indicator and a TTL signal output instructions;
2, with the switching signal DO?TTL?And AO output analog signal output;
3, TTL output valid signal is low.?When the output low signal light can be directly connected microcontroller or relay module?
4, analog output 0 ~ 5V voltage, the higher the concentration the higher the voltage.
5, pane, butane, LPG, LNG has detection sensitivity.
6, there are four screw holes for easy positioning;
7 duct Dimensions: 32 (L) * 20 (W) * 22 (H)
8, with a long life and reliable stability
9, fast response and resume

Electrical perties:
Input voltage: DC5V Power?Electric current?: 150mA
DO output: TTL digital 0 and 1?0.1 and 5V?
AO Output: 0.1-0.3V?Relatively clean?, The maximum concentration of a voltage of about 4V
reminder: After the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is a normal phenomenon, because the internal heating wire, hot if not normal.
