Smart Building Management System Using ESP32

This paper presents a Smart Building Management System utilizing ESP32 to automate essential home functions, enhancing energy efficiency and convenience. In many homes and buildings, tasks like turning lights on or off, checking water levels, or opening doors are still done manually, leading to energy waste, inconvenience, and lack of monitoring. To solve this, our project introduces a Smart Building Management System using the ESP32 microcontroller. The system uses sensors such as the Light Dependent Resistor (LDR) for light detection, Passive Infrared (PIR) sensor for motion sensing, Infrared Obstacle Avoidance sensor (IR) for object detection, and HC-SR04 Ultrasonic Distance Sensor for water level monitoring. It also uses ThingSpeak to store and display sensor data in real-time graphs. This automation reduces manual effort, saves electricity, and adds safety to the environment. The uniqueness of the project lies in combining all these functions into a single system that is low-cost, easy to use, and can be controlled and monitored remotely.
