Smart Load Control and Gas Detector

Abstract

Energy management and safety are critical in modern households of Bangladesh, where manual load control often leads to significant wastage and undetected gas leaks pose severe risks of accidents. The reliance on traditional switches results in unnecessary electricity consumption, particularly in urban areas with high demand, while gas-related incidents due to poor monitoring contribute to fires and health hazards. This project proposes an Arduino-based smart system to automate load control and detect gas leaks efficiently. Using Arduino Uno as the core, the system integrates capacitive touch sensors for local control, HC-05 Bluetooth for remote operation via a mobile app, MQ-2 sensor for gas monitoring, and ISD1820 module for voice alerts. Data acquisition processes allow real-time toggling of up to four loads and immediate notifications upon threshold breaches. The proposed system is simulated in Proteus software to report detailed performance, with reports accessible through the app. Arduino software is used for simulation results and embedded hardware kit will be fabricated
