MQ-6 Cảm biến phát hiện khí ga Butan 

 

---------------------------

 

MQ-6 Sensor Profile:
sensitive material MQ-6 gas sensors used in the clean air, the lower the conductivity of tin oxide (SnO2). When present in the environment of flammable gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-6 gas sensor for propane, butane, LPG ​​high sensitivity, natural gas and has a good sensitivity. The sensor can detect a variety of combustible gas, is a low-cost sensors for a variety of applications

 Suitable for the home or industry to the LPG (liquefied petroleum gas), butane, propane, LNG (liquefied natural gas) detector. 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, with DO switching signal (TTL) output and analog output AO;3, TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay modules) 4, analog output 0 ~ 5V voltage, the higher the concentration, the higher voltage. 5, propane, butane, LPG, LNG better 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 recovery characteristics

Test program:
