The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for fuel leakage detection (home and enterprise). It is appropriate for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast reaction time, measurement may be taken as soon as possible. The sensitivity of the sensor can be adjusted through the potentiometer.
