Sensitive material MQ-6 gas sensor is used to clean the air in the lower Conductivity of tin dioxide (SnO2). When there is the environment in which the combustible gas sensor , conductivity sensor with increasing concentration of combustible gases in air increases . Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-6 gas sensor for propane , butane , liquefied petroleum gas sensitivity is high, natural gas and has a good sensitivity. This sensor can detect a variety of flammable gas , is a low-cost sensors for a variety of applications
Suitable for home or industrial LPG ( liquefied petroleum gas ) , butane , propane , LNG ( liquefied natural gas ) detection devices. Excellent resistance to ethanol vapor , smoke interference
Module Features :
1. using high-quality dual-panel design, with power indicator and TTL signal output instructions;
2. the switching signal having a DO (TTL) output and analog output AO ;
3. TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
4. 0 ~ 5V analog output voltage , the higher the concentration the higher the voltage .
5. propane , butane , LPG, LNG has a good detection sensitivity.
6. there are four screw holes for easy positioning ;
7. Product dimensions : 32 (L) * 20 (W) * 22 (H)
8. has a long life and reliable stability
9. rapid response and recovery characteristics
