Features:
The MQ-135 is a semiconductor-based air quality sensor designed to detect a wide range of harmful gases, including ammonia, hydrogen sulfide, benzene vapors, smoke, and other pollutants. It operates through conductivity changes in SnO2 material when exposed to gases. With high sensitivity, low power requirements, and cost efficiency, it's ideal for indoor and industrial air monitoring.

Specifications:
  • Model: MQ-135
  • Sensor type: Semiconductor
  • Target gases: Ammonia, sulfide, benzene vapors, smoke, hydrogen
  • Detection range: 10 to 1000 ppm (varies by gas)
  • 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: <=950 mW
  • Sensitivity: Rs (in air) / Rs (400 ppm H2) >=5
  • Output voltage (Vs): 2.0V to 4.0V in 400 ppm H2
  • Concentration slope (alpha): <=0.6 (R400ppm / R100ppm H2)
  • Standard operating temp: 20C +-2C
  • Standard humidity: 55% +-5% RH
  • Preheat time: Over 48 hours
