Description: 

 

This kit contains the required components to build yourself a petroleum gas detector. 
This module is based on a LM393 I.C. and a MQ5 sensor. 

 

While being a simple soldering project for beginners, this kit can be used in a variety 
of small personal, educational or enterprise applications such as: 

 

 

Liquid Petroleum Gas Detector for 5v Microcontrollers (Analog/Digital) 

 

 

Natural Gas Detector for 5v Microcontrollers (Analog/Digital) 

 

This is a D.I.Y. kit that requires soldering through-hole components on the main single-
sided printed circuit board (PCB). Users with minimal soldering tools and intermediate 
skills can easily assemble this module. The assembly process should take anywhere 
between 10 to 20 minutes.
