Description:

The MQ-5 Gas Sensor module is useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible.

  • Sensitive for LPG, natural gas, coal gas
  • Output voltage boosts along with the concentration of the measured gases increases
  • Fast response and recovery
  • Adjustable sensitivity
  • Signal output indicator

Note!:

The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which cannot be done with a single gas sensor. If your project is aimed at obtaining the gas concentration at a very precise level, then we do not recommend this gas sensor.

Features:

  • Using high-quality dual-panel design, with power indicator and TTL signal output instructions
  • With a DO switch signal (TTL) output and AO analog signal output
  • TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
  • The analog output voltage, the higher the concentration the higher the voltage
  • For gas, natural gas has better detection sensitivity.
  • There are four screw holes for easy positioning

Electrical Specifications:

  • Input voltage: 5V DC power
  • Input current: 150mA
  • DO output: TTL digital 0 and 1 (0.1 and 5V)
  • AO output :0.1-0 .3 V (relatively clean), the highest concentration of voltage around 4V
