Integration of MQ-5 Gas Sensors with Arduino Board

Abstract

This research paper explores the integration and application of the MQ-5 gas sensor with an Arduino microcontroller for a CubeSat satellite project aimed at detecting and analyzing gaseous environments in space. The MQ-5 sensor, known for its sensitivity to gases such as LPG, methane, and hydrogen, it was selected for its cost-effectiveness and dependability across diverse atmospheric conditions. The main goal was to develop a compact and efficient gas detection system suitable for the constrained environment of a CubeSat. The study covers the complete process from hardware setup to data analysis. Initial stages involved configuring the MQ-5 sensor with the Arduino, followed by rigorous calibration procedures using known gas concentrations to ensure accurate measurement. Calibration data was employed to develop a strong mapping function for converting raw sensor readings into accurate gas concentration levels.
