Features:
The MQ-8 is a semiconductor sensor designed for detecting hydrogen gas (H2). It uses a SnO2 sensing layer that increases conductivity in the presence of hydrogen, delivering a signal readable via a simple circuit. With strong selectivity for hydrogen and resistance to interference from other gases, it offers a reliable, cost-effective solution for hydrogen detection in residential and industrial environments.

Specifications:
  • Model: MQ-8
  • Sensor type: Semiconductor
  • Detection gas: Hydrogen (H2)
  • Concentration range: 100 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): 29 ohm +-3 ohm at room temp
  • Heater power consumption: <=900 mW
  • Sensitivity: Rs (in air) / Rs (in 1000 ppm H2) >=5
  • Output voltage (Vs): 2.5V to 4.0V (in 1000 ppm H2)
  • Concentration slope (alpha): <=0.6 (R1000ppm / R400ppm H2)
  • Operating temp: 20C +-2C
  • Humidity: 55% +-5% RH
