MQ-6 LPG Gas Sensor Module

Features:

LPG (liquefied petroleum gas), LNG (liquefied natural gas) detection.
The use of high quality dual panel design, with power and TTL signal output indicator;
With DO switch signal (TTL) output and AO analog signal output.
TTL output signal is low level. (when the output is low, it can be directly connected to the microcontroller or relay module).
Analog output voltage, the higher the concentration of higher voltage.
The detection of gas, natural gas has better sensitivity.
Four screw holes for positioning.
Long service life and reliable stability
Rapid response recovery characteristics
