MQ-6 LPG LNG Gas detection sensor module

Production description

Module Applications:
Suitable for domestic or industrial on 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, with a DO switch signal (TTL) output and AO 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, 0 ~ 5V analog output voltage, the higher the concentration the higher the voltage.
5, the 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, with a long service life and reliable stability
9, rapid response and recovery characteristics
 
Electrical properties:
Input voltage: DC5V power (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output :0.1-0 .3 V (relatively clean), the highest concentration of voltage around 4V
