README
README.mdGas-Detection-System
This project is a gas detection system using the MQ-6 sensor and ATmega32 microcontroller.It includes hardware design, PCB layout, and assembly programming.
Features
This system detects flammable gases such as LPG, Methane, and Propane using the MQ-6 sensor. It provides real-time gas concentration display on an LCD and triggers LED alerts when dangerous levels are detected.Designed using KiCad and programmed in Assembly (AVR), it ensures low power consumption and can be adapted for both home and industrial applications.

Questions
What parts does the Gas Detection PCB use?
26 parts, built around the ATMEGA32L-8PU and MQ-6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Gas Detection PCB KiCad files?
From the mara-chiosea/Gas-Detection-System repository on GitHub, at the commit this page was made from: the board is KiCad/Gas_Detection_PCB.kicad_pcb and its schematic KiCad/Gas_Detection_Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gas Detection PCB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
