The Grove – Gas Sensor(MQ-2 MQ2 Smoke Sensor Module in Pakistan) module is useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer.
Main Chip: The LM393, MQ – 2 Gas Sensor Working Voltage: DC 5 V Great for home or factory gas leakage detection Use for Detecting: Combustible gas such as LPG, butane, methane, alcohol, propane, hydrogen, smoke, etc
