EASY plug Analog Gas Sensor

Introduction

This analog gas sensor - MQ2 is used in gas leakage detecting equipment in consumer electronics and industrial markets.
This sensor is suitable for detecting LPG, I-butane, propane, methane, alcohol, Hydrogen and smoke. It has high sensitivity and quick response.
In addition, the sensitivity can be adjusted by the potentiometer.
This module should be used together with EASY plug control board.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.


Features

  • Connector: Easy plug
  • Power supply: 5V
  • Interface type: Digital and Analog
  • Wide detecting scope
  • Simple drive circuit
  • Stable and long lifespan
  • Quick response and High sensitivity


Technical Details

  • Dimensions: 56mm*20mm*18mm
  • Weight: 9g


Connect It Up

Connect the EASY Plug analog gas sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.
