Abstract

This study addresses common challenges in conventional home electricity usage, focusing on safety concerns related to gas leakage. The current technology lacks immediate power usage tracking, and manual control of circuit breakers, sockets, and lamps proves challenging, particularly when users are away. To overcome these issues, this project employs an Esp8266 Wi-Fi Shield Arduino as a microcontroller connected to sensors and a servo motor. The system detects gas leakage, controls lamp and socket activation, and manages the RCCB with the servo motor by utilizing Blynk apps for monitoring. The study's objective is to design a centralized system enabling the control and management of home electrical appliances via smartphone. This methodology involves developing a microcontroller program for the Cytron ESP8266 WiFi Shield, creating an auto-reclosure circuit breaker notification, and building a practical gas leakage detection prototype for household application. Additionally, the system addresses lightning-induced overvoltage issues, analyzing nuisance tripping and providing control over home appliance usage while effectively detecting hazardous gas leaks. The approach is based on Blynk and the Esp8266 Wi-Fi Shield Arduino by incorporating data from limit switch conditions, relay status, voltage sensors, current sensors, and power consumption. The results justify the servo's efficient performance, reliable relay operations, and precise gas sensor triggering. Despite slight variations in current and voltage values compared to the actual meter, the system offers a successful and systematic approach to enhance home electricity management and safety.
