MQ-2 Smoke/LPG/CO Gas Sensor

The Analog Smoke/LPG/CO Gas Sensor(MQ2) module utilizes an MQ-2 as the sensitive component and has a protection resistor and an adjustable resistor on board. The 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 in family and industry. The resistance of the sensitive component changes as the concentration of the target gas changes. Features Power supply needs: 5V Fast response and High sensitivity Wide detecting scope Simple drive circuit,Stable and long life Application Domestic gas leakage detector Industrial gas detector Portable gas detector.
