CMU MQ5 LPG GAS SENSOR BOARD

SKU: CMU MQ5 LPG GAS SENSOR BOARD

BRAND: Communica


Adjustable Gas Sensor for--Hydrogen (H2), LPG, Methane-Natural Gas (CH4), Carbon Monoxide (CO), and Alcohol. Detects 300-10,000PPM

Overview

Suitable for home or industrial on LPG, natural gas, coal gas monitoring devices. Excellent resistance to alcohol, smoke interference.

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;
  • Product Dimensions : 32 x 20 x 22
  • With a long service life and reliable stability
  • Rapid response and recovery characteristics
