MQ-5

Working Principle:

A gas sensor is a device which detects the presence of gas in an area.This sensor interacts with a gas to measure its concentration. Each gas has.The MQ5 gas sensor detects the presence of various gases such as hydrogen, carbon monoxide, methane and LPG ranging from 100ppm to 3,000ppm

 

Pin Configuration:

Vcc: 5v

GND: GND

A0: Analog pin (A0 to A5)

D0: Digitl pi(2 to 13)

 

Advantages:

  • Output voltage boosts along with the concentration of the measured gases increases
  • Fast response and recovery
  • Adjustable sensitivity
  • Signal output indicator

 

Applications:

  • Gas leakage detector
  • Air quality monitor
  • Detection of harmful gases
  • Domestic air pollution detection
  • Industrial pollution detection
  • Portable air pollution detection
