The analog gas sensor - MQ2 is used in gas leakage detecting equipments in consumer and industry markets. This sensor is suitable for detecting LPG, i-butane, propane, methane, alcohol, Hydrogen, smoke. It has a high sensitivity and fast response time. The sensitivity can be adjusted by the potentiometer.

Features

  • Standard assembling structure (Times-of-5mm Center distance between two 3mm mounting holes)
  • Easily recognitive interfaces of sensors ("A" for analog and "D" for digital)
  • Icons to simply illustrate sensor function 
  • High quality connector
  • Immersion gold surface

Specification

  • Power supply needs: 5V
  • Interface type: Analog
  • Wide detecting scope
  • Fast response and High sensitivity
  • Simple drive circuit
  • Stable and long life
  • Size: 36.4 x 26.6 mm
