MQ-6 LPG & Butane Gas Sensor Module
The MQ-6 LPG & Butane Gas Sensor Module is designed for detecting concentrations of liquefied petroleum gas (LPG), propane, and butane in the air. Utilizing a sensitive SnO₂ (tin dioxide) layer, the sensor exhibits lower conductivity in clean air and higher conductivity when combustible gases are present. This change in conductivity is converted into an output signal corresponding to gas concentration levels. The module offers both analog and digital outputs, allowing for flexible integration into various detection systems. Its fast response time and high sensitivity make it suitable for applications requiring prompt gas leak detection.
Features
- High sensitivity to LPG, propane, and butane gases.
- Detects gas concentrations ranging from 200 to 10000ppm.
- Provides both analog and digital output signals.
- Fast response and recovery times for timely detection.
- Simple drive circuit for easy implementation.
- Long service life with stable performance.
- Adjustable sensitivity via onboard potentiometer.
- Compact design suitable for various applications.
