Product Description

Details

Introduction
The Analog Smoke/LPG/CO Gas Sensor (MQ - 2) module utilizes an MQ-2 as the sensitive component and has a protection resistor and a potentiometer on board.
The MQ-2 gas sensor is sensitive to LPG, i-butane, propane, methane, alcohol, Hydrogen and smoke.
It could be used in gas leakage detecting equipment in family and industry.
The resistance of the sensitive component changes as the concentration of the target gas changes.

Package Included
-1 x RTC-DS1302 module
-1 x 5-Pin anti-reverse cable

Good startup project for Home/Shop Safety By Carl 2016-07-26 00:03:42

Great sensor for Arduino or Rasphberry Pi project or stand alone detection system. Fully adjustable alarm point and output allows you to make it a warning system for gas buildups in remote locations even without a connection to a PLC. When connected to a PLC (Arduino or Rasphberry PI) it server well as a gas detection data logger and can be connected to real world remote devices with WiFi or cloud access. Good for home safety and shop warning systems or even portable leak detection devices. Open source code available with search of "Arduino Gas Detector"

Great project for home safety By Techplay 2016-07-25 23:31:50

Nice design, compact with secondary output which can be useful for backup alarm if not monitored regularly or in a remote location. Good sensitivity to gas with adjustable alarm point. Good for enclosed environments where gas may build up. You can find links for these types of device by searching Arduino Gas Detector Projects and Code example are full compatible with this unit.
