MQ-6 Propane Isobutane LPG Gas Sensor Module
The MQ-6 is a tin oxide (SnO2) semiconductor gas sensor module designed for detecting combustible gases like LPG (propane/butane) and isobutane within a 200-10000 ppm range. Operating at 5V DC, it provides both analog voltage and digital TTL-level outputs for easy integration with microcontrollers like Arduino, Raspberry Pi, and industrial ADCs.
Features
- Tin oxide (SnO2) semiconductor sensor for LPG, propane, butane, and isobutane detection.
- Wide detecting range from 200 to 10,000 ppm with adjustable sensitivity via onboard potentiometer.
- Dual output: 0-5V analog voltage signal and digital TTL-level signal for direct microcontroller interface.
- Simple 5V DC drive circuit with fast response and recovery characteristics.
- Compact module design (32mm x 20mm) suitable for portable detectors and fixed monitoring systems.

The MQ-6 gas sensor module utilizes a tin dioxide (SnO2) sensing element whose conductivity increases in the presence of combustible hydrocarbon gases. When the target gas interacts with the heated SnO2 surface, a change in resistance occurs, which is converted into a corresponding analog output voltage (0-5V) proportional to gas concentration. A comparator circuit provides a digital TTL output that switches low when a preset threshold is exceeded.
Designed for reliability in varied environments, the module operates within -20°C to 40°C and at relative humidity below 95% RH. Its simple interface and robust construction make it suitable for integration into prototype boards, educational kits, and cost-sensitive industrial safety systems requiring continuous combustible gas monitoring.
