Features:
The MQ-5 is a semiconductor-based gas sensor designed for detecting flammable gases, particularly LPG (propane), methane, and butane. It responds to gas concentration by increasing conductivity, producing an output voltage that can be read through a simple circuit. With strong sensitivity, low cost, and reliable performance, it is suitable for home and industrial gas detection systems.

Specifications:
  • Model: MQ-5
  • Sensor type: Semiconductor
  • Detection gases: LPG (propane), methane (CH4), butane (C3H8)
  • Concentration range: 300 to 10000 ppm
  • Loop voltage (Vc): <=24V DC
  • Heater voltage (Vh): 5.0V +-0.1V (AC or DC)
  • Load resistance (RL): Adjustable
  • Heater resistance (Rh): 26 ohm +-3 ohm at room temp
  • Heater power consumption: <=950 mW
  • Sensitivity: Rs (in air) / Rs (in 2000 ppm C3H8) >=5
  • Output voltage (Vs): 2.5V to 4.0V (in 2000 ppm C3H8)
  • Concentration slope (alpha): <=0.6 (R3000ppm / R1000ppm C3H8)
  • Operating temp: 20C +-2C
  • Humidity: 55% +-5% RH
  • O2 concentration: >=18%
  • Preheat time: >=48 hours
