MQ6 - LPG Propane Gas Sensor Module
Description:
MQ6 Gas Sensor Module is a popular and widely used gas detection module designed for detecting the presence of combustible gases, especially LPG (Liquefied Petroleum Gas), propane, butane, methane, alcohol, and hydrogen in the air. It operates based on a sensitive material (SnO₂ - Tin Dioxide) whose conductivity increases with the concentration of target gases.
Features:
1. High sensitivity to LPG, propane, and butane
2. Fast response time and recovery
3. Adjustable sensitivity via onboard potentiometer
4. Dual signal output: Analog & Digital
5. Long life and low cost
6. Stable and reliable performance
7. Operating Voltage: 5V DC
