Automated Building Management Using Embedded IoT

Abstract

The “Automated Building Management Using Embedded IoT” project is designed to enhance the efficiency, comfort, and security of building operations by integrating embedded IoT technology into a centralized management system. This system automates the monitoring and control of various building functions, including HVAC (Heating, Ventilation, and Air Conditioning), lighting, security, energy management, and water usage. By leveraging IoT sensors and embedded systems, the solution provides real-time data and automated responses, enabling facility managers to optimize resource usage, reduce operational costs, and improve the overall occupant experience. This project is particularly suitable for commercial buildings, residential complexes, and industrial facilities aiming to implement smart building technologies for improved management and sustainability.

Existing System

Traditional building management systems (BMS) are often fragmented, with separate systems handling HVAC, lighting, security, and energy management. These systems typically operate independently, lacking integration and real-time data processing capabilities. As a result, facility managers are unable to monitor and control building functions efficiently, leading to higher operational costs, energy waste, and suboptimal occupant comfort. Manual intervention is often required to manage building operations, which is time-consuming and prone to errors. Additionally, existing systems may not support remote monitoring or automated responses, limiting the ability to respond promptly to issues such as equipment failures or security breaches.

Proposed System

The proposed “Automated Building Management Using Embedded IoT” system integrates various building functions into a single, intelligent platform that provides real-time monitoring, control, and automation. The system utilizes IoT sensors and embedded systems to collect data on key building parameters, such as temperature, occupancy, energy consumption, and security status. This data is transmitted to a central platform, where it is processed and analyzed to optimize building operations. The system automates routine tasks, such as adjusting HVAC settings based on occupancy, controlling lighting based on natural light levels, and monitoring security systems for unauthorized access. Additionally, the system supports remote monitoring and control via a mobile or web interface, allowing facility managers to manage building operations from anywhere.
