MQ135 MQ-135 air quality sensor module hazardous gas detection sensor

Specification MQ135:

VCC: positive power supply (5V)
GND: negative one
DO: TTL switching signal output
AO: Analog output

Characteristics MQ135:

  • using high-quality dual-panel design, with power indicator and TTL signal output instructions
  • with a DO switch signal (TTL) output and analog output AO
  • TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
  • the higher the voltage, the concentration of the analog output voltage is higher
  • air quality, hazardous gas detection have better sensitivity
  • there are four screw holes for easy positioning
  • Product dimensions: 32 (L) * 20 (W) * 22 (H)
  • with a long life and reliable stability
  • rapid response recovery characteristics
