CMU MQ3 GAS SENSOR MODULE

SKU: CMU MQ3 GAS SENSOR MODULE

BRAND: Communica


High Sensitivity Fast Response Alcohol Gas Sensor used in Breathalyser-Mounted on Board with Sensor. Adjust-Used with Arduino etc.

Overview

Features

  • High quality double panel design, with power indicator and TTL output signal.
  • Have DO switch signal(TTL) output and AO analog signal output.
  • TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can be directly connect single chip microcomputer or relay module)
  • Analog output voltage with concentration, the higher concentration, the higher voltage.
  • Has better sensitivity with the liquefied petroleum gas, natural gas, city gas, smoke.
  • Has long service life and reliable stability
  • Rapid response recovery features
