Air Quality and Hazardous Gas Detection using IoT for Household and Industrial Areas

The detection and monitoring of hazardous gases is essential for ensuring the safety individuals in various settings, such as industrial environments residential areas. gas detectors detect like LPG, NH3, alcohol, NOx, Benzene, CO2, Alcohol, Propane, Hydrogen, Methane, Carbon Monoxide, smoke area around them. In this study, we present a system real-time using MQ135 MQ2 sensors. consists monitor that placed fixed location mobile device can be carried by user. sensor used to ammonia, while carbon monoxide hydrocarbons. Each these known through Parts per Million (PPM) values determined which it is. utilises microcontroller process data display concentrations on user interface. also has capability alert send notifications an accompanying App if exceed predetermined threshold. reliable, accurate, easy use, making ideal solution detecting mitigating risks associated with settings. was tested able accurately presence reliable convenient real-time.
