Sensitive material of gas sensor is SnO2 with lower conductivity in clean air. When combustible gas exists, the sensor conductivity rises with gas concentration. MQ-2 gas sensor is sensitive to LPG, i-butane, propane, methane, alcohol, hydrogen and smoke. It could be used in gas leakage detecting equipments at home as well as in industry too. The resistance of the sensitive component changes as the concentration of the target gas changes.
- Continuous Analog output
- Low cost
- Compact size
