Gas Sensor(MQ5) module is useful for gas leakage detection (in home and industry). It can detect LPG, natural gas, town gas and so on. Because it has a fast response time once it has pre-heated, measurements are almost instantaneous. Note that the sensitivity can be adjusted by the potentiometer.
Features
- High sensitivity to LPG, natural gas, town gas
- Low sensitivity to alcohol and smoke
- Fast response
- Stable and long life
Application Ideas
- Gas leakage detection
- Toys
