This section describes how to read analog data from the MQ-2 gas sensor using the ESP32 and convert the readings to an approximate PPM (parts per million) value. Using the Arduino IDE, write code to ...

The system will integrate a gas sensor (such as an MQ-2 or MQ-5 sensor) with a microcontroller-based circuit to continuously monitor the surrounding air for LPG concentrations. If the gas level ...

Abstract: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...

Abstract: Indoor pollution is a major cause of worry in homes and other enclosed environments. It is possible that prolonged exposure to the residues of heavy metals and particulate matter released ...
