Product description
MQ-6 semiconductor sensor for LPG. The sensitive material in the MQ-6 gas sensor is SnO2, which has low conductivity in clean air. When the target gas (flammable gas) is present, the sensor’s conductivity increases with the gas concentration. A simple electronic circuit can be used to convert this change in conductivity into a corresponding output signal representing the gas concentration. MQ-6 has high sensitivity to LPG. Compared to MQ-5, MQ-6 has higher sensitivity to heavier hydrocarbons (butane/propane).
The sensor can be mounted on a suitable breakout board 41004066.
Specifications:
- High sensitivity to LPG: butane (C4H10), propane (C3H8)
- Supply voltage: 5 V
- Power: 950 mW (the sensor becomes hot during operation)
- Detection range: 300–10,000 ppm
- Dimensions: Ø19.5 × 24 mm (with pins)
Applications:
- Gas leak detector for car, boat, motorhome, and LPG-based gas installations in the home
- Industrial detector for flammable gases
- Portable gas detector
- Popular sensor – many available examples for different platforms
