Home Automation and Monitoring System using Internet of Things

The integration of Internet of Things (IoT) devices in smart homes has revolutionized the way we interact with our living spaces. In this paper, we present a comprehensive smart home innovation aimed at enhancing safety and comfort. Our system includes several IoT devices controlled through a mobile application for seamless user interaction. A mobile controlled LED bulb, integrated with the Blynk app, provides users with remote lighting control. Live data from an MQ 5 gas sensor is monitored through the mobile application, triggering the activation of a fan in case of gas leakage, ensuring safety within the home environment. An infrared (IR) sensor detects human presence, enabling an automatic pump system for convenient water usage. Additionally, another IR sensor is employed to detect human presence and illuminate mini lights for safer navigation, particularly on staircases. The system is built using Node MCU, providing a cost effective and efficient solution for smart home automation. Through the integration of these IoT devices, our smart home innovation aims to provide users with a safer, more comfortable, and energy efficient living environment. This paper presents the design, implementation, and performance evaluation of our smart home system, demonstrating its effectiveness in enhancing the quality of life for homeowners.
