Smart Home Automation Using Cloud Computing and ESP32

Abstract

The Internet of Things (IoT) consist of interconnected devices with unique identities that communicate over the internet. Essentially, it enables the connection and monitoring of various sensors and devices online. This advancement has facilitated home automation and monitoring, enchancing convenience and security in daily life.
This paper explores IoT-based sensing and monitoring systems for implementing automated homes. The proposed prototype utilizes an ESP32board, which connects to the internet and can be remotely controlled via Android or iOS smartphone. Acting as the core component, the ESP32 functions as a micro web server and serves as an interface for multiple hardware modules. The system provides switching functionalities to control home appliances such as lights and fans via a relay system. As technology progresses, homes are becoming increasingly intelligent, transitioning from traditional switches to centralized control systems with remote-controlled operations. Conventional wall switches, positioned throughout the house, can be inconvenient for users, particularly for the elderly or individuals with physical disabilities. A remote-controlled home automation system, managed via a smartphone, offers a modern solution. To achieve this, the system employs a microcontroller board with a built-in Wi-Fi module on the receiver end. Meanwhile, on the transmitter end, a graphical user interface (GUI) application on a smartphone sends ON/OFF commands to the receiver, controlling connected devices. By simply tapping designated areas on the GUI, users can remotely operate appliances, making home autiomation more efficient and accessible.
