I built an indoor air quality monitor to monitor air temperature and humidity using the DHT22 sensor. It also has an MQ-2 gas sensor to monitor LPG, smoke, and CO molecules in the air.

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: Gas leaks are one of the big problems in the industrial sector, even starting to spread to other sectors. One of the solutions to reduce losses due to gas leakage is to detect it early when ...
