MQ-135 Air Quality Gas Sensor

This Air Quality Sensor to detect NH3, NOx, alcohol, Benzene, smoke and CO2 concentrations in the air. An analog signal increases as the concentration of pollutants increase in the air. This module also includes a digital output pin with TTL output. The Potentiometer on board is used to set the Digital Output Set point.

Features:
– Useful for detecting harmful gases in the environment including ammonia, sulfide, benzene vapor, smoke, etc.
– Wide detecting scope
– Sulfide, benzene Department of steam, smoke and other harmful gases with high sensitivity
– Rapid response recovery characteristics
– High sensitivity & stability
– Simple drive circuit

Specifications:

  • Size: 32X20X22mm/1.25*0.78*0.86”
  • The main chip: MQ135 gas sensing probe
  • Operating voltage: DC 5V
  • Current: 150mA
  • DO Output: 0.1V/5V
  • AO Output: 0.1-0.3V
  • Signal output indicator instructions
  • Dual signal output (analog output, and TTL level output)
  • TTL output valid signal is low; (output low signal light, which can be accessed microcontroller IO port)
  • Analog output with increasing concentration, the higher the concentration, the higher the voltage Sulfide, benzene Department of steam, smoke and
  • other harmful gases with high sensitivity
  • Has a long life and reliable stability
