Deploying an IoT-enabled Integrated Comprehensive Home Automation System using WSN for Enhanced Continuous Optimization and Fault Identification System

Abstract

Nowadays, there is a concept of making the home smart, which reduces human efforts means we cannot operate, monitor, and look after electrical appliances or the environment. In other words, conventional home systems cannot change their state instantly based on different situations. This article proposes a smart home automation system combining multiple Internet of Things (IoT) techniques for secure and power-efficient control of the home environment designed with the user in mind. Entry is through an RFID reader, which asks users to swipe their card on the sensor for access. If the verification passes, the door unlocks, and the yellow LED lights up; otherwise, the red LED lights up. Within the house, there are also temperature and humidity sensors and gas sensors scattered throughout, which provide feedback data to be displayed on an LCD. When the level of gas crosses a limit, an email message goes to the house owner with a buzzer warning inside the home. There would be remote control of lights at home with the matching Blynk app and further voice-controlled features over Google Assistant. In the case of a water tank, an automated system using ultrasonic sensors to detect levels and control pump action when needed (so as not to run dry or overfill) includes status updates provided in the Blynk app. Also, it has a single-axis solar tracking system with LDR sensors for optimal alignment of the solar panel to get maximum energy from sunlight. It also comprises a rain sensor together with a servo motor that closes windows whenever there is precipitation or rain, in addition to home safety and convenience. This system helps to improve safety, comfort and energy management in the home by using IoT technologies that are used for controlling lighting or climate control systems manually.
