The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (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, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer.
MQ-2 gas sensor using gas sensitive material is to be clean air in the lower conductivity of Tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the conductivity of the sensor with an increasing concentration of combustible gas in the air increases.
Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas.
Good sensitivity to Combustible gas in a wide range
High sensitivity to LPG, Propane, and Hydrogen
Long life and low cost
Simple drive circuit
Can be used as a Digital or analog sensor
The Sensitivity of Digital pin can be varied using the potentiometer
Can be used to Measure or detect LPG, Alcohol, Propane, Hydrogen, CO and even methane.
