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 MQ2 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:
Methane, Butane and LPG Detector for Microcontrollers (Analog/Digital)
Methane, Butane and LPG Detector for Arduino (Analog/Digital)
Methane, Butane and LPG Detector for Raspberry Pi (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.
