The SEGi University Smart AC Management System is an Internet of Things (IoT) project designed to address the challenge of energy waste in the university's electrical labs. Split-unit air conditioners are often operated inefficiently, leading to significant energy consumption and increased costs. This system provides a smart, automated solution, utilizing distributed sensors and microcontrollers, to optimize AC usage, enhance occupant comfort, and contribute to SEGi University's sustainability goals.
The SEGi Smart AC Management System is a comprehensive, distributed IoT solution designed to address these challenges. By leveraging a network of ESP8266 and ESP32 microcontrollers, along with precise current transformers and environmental sensors, this system intelligently automates AC control, optimizes energy usage, and enhances occupant comfort. The system utilizes a Raspberry Pi 5 as a central server, hosting the user interface and coordinating communication between the distributed components. This distributed architecture allows for greater flexibility, scalability, and responsiveness compared to a centralized approach.
Automatically adjusts AC operation based on the presence of people in the lab, eliminating energy waste in empty spaces. Uses a wide-angle fisheye camera with IR capabilities for improved coverage and night vision.
Allows facilities managers to monitor energy consumption, adjust AC settings, and troubleshoot issues from anywhere via a user-friendly web interface.
Maintains a comfortable temperature range using a PID controller and heat index calculations, ensuring a pleasant environment for lab occupants.
Utilizes ESP8266 microcontrollers for individual AC unit control and ESP32 for environmental and current monitoring, providing a more granular and responsive system.
Employs SCT-013 current transformers to accurately measure the power consumption of each AC unit, enabling detailed energy usage analysis.
Includes a BME280 sensor to monitor temperature, humidity, and pressure, providing a comprehensive understanding of the lab's environmental conditions.
Enables the system to control existing split-unit ACs via IR signals, making it a cost-effective solution without requiring AC unit replacements.
Provides different user roles (Admin, Moderator, Trusted User, User) with varying levels of access, ensuring system security.
