Development of Smart Home Automation System

Abstract

The Smart Home Automation System represents a holistic approach to modern residential living, leveraging embedded systems to create a comprehensive and intuitive environment. This multifaceted system integrates various modules designed to enhance safety, convenience, and resource management within the home. It encompasses diverse functionalities such as boundary safety measures employing continuous beams with a buzzer alert system to prevent unauthorized access, ensuring a secure perimeter. Moving to the garden area, the system orchestrates an Automation Irrigation System, orchestrating the water supply through a 6V pump based on soil sensor readings. This intelligent irrigation not only fosters optimal plant growth but also conserves water resources by delivering moisture precisely where needed. Complementing this, an Automatic Light Control system utilizing Light Dependent Resistors (LDRs) regulates LED garden lighting according to ambient light levels, optimizing energy consumption without compromising illumination. Efficient water management extends to an Automatic Water Tank Level Controlling System, seamlessly managing water levels with the 6V pump, mitigating overflow risks, and ensuring an uninterrupted water supply. Enhancing security and accessibility, an Automatic Main Gate system detects approaching vehicles, automatically opening and closing the gate, providing seamless access control. Once within the premises, a secure home gate opens via a fingerprint sensor connected to an electronic actuator, granting authorized entry. Safety mechanisms further fortify the system with Fire and LPG Gas Leakage detection using MQ and IR rx sensors coupled with audible alerts, promptly addressing emergencies. Additionally, Passive Infrared (PIR) sensors detect human presence in rooms, intelligently controlling 5mm white LED lights to conserve energy in unoccupied spaces, optimizing efficiency.
