Abstract

The advancement of Internet of Things (IoT) technology has enabled the development of smart home automation systems aimed at enhancing comfort and maximizing energy efficiency. This study focuses on the development and implementation of a real-time web-based intelligent cooling system for a bedroom environment. The primary concerns identified are thermal discomfort resulting from increased room temperatures and the inadequate performance of lighting and cooling systems. The proposed system employs an ESP32 microcontroller, a DHT22 temperature sensor, a PIR motion sensor, and an LDR light sensor, together with actuators including a servo-controlled fan and LED lights. The ESP32 is configured as a local web server, enabling real-time monitoring through an HTTP connection. Experimental results suggest that the system can autonomously activate the cooling fan when the room temperature exceeds 30°C and promptly adjust illumination based on ambient light levels. Real-time synchronization between physical components and the web dashboard enables continuous monitoring of WiFi connectivity, light intensity, and fan position. The suggested system offers an efficient and easily monitored smart cooling solution for bedrooms, suggesting the potential to enhance household energy efficiency through automated device management.
