Features:
The MQ-2 is a semiconductor gas sensor that detects combustible gases and smoke, including LPG, propane, butane, hydrogen, and methane. It senses changes in SnO2 conductivity when exposed to gas, offering high sensitivity, long lifespan, and ease of use. Ideal for gas leak detection in homes and industrial systems.

Specifications:
  • Model: MQ-2
  • Sensor type: Semiconductor
  • Detection gases: LPG, propane, butane, hydrogen, methane, smoke
  • Concentration range: 300 to 10000 ppm (combustible gases)
  • Loop voltage (Vc): <=24V DC
  • Heater voltage (Vh): 5.0V +-0.2V (AC or DC)
  • Load resistance (RL): Adjustable
  • Heater resistance (Rh): 31 ohm +-3 ohm at room temp
  • Heater power consumption: <=900 mW
  • Sensing resistance (Rs): 2k ohm to 20k ohm (in 2000 ppm C3H8)
  • Sensitivity: Rs (in air) / Rs (in 1000 ppm isobutane) >=5
  • Concentration slope (alpha): <=0.6 (R5000ppm / R3000ppm CH4)
  • Standard operating temp: 20C +-2C
  • Standard humidity: 65% +-5% RH
  • Preheat time: Over 48 hours
