This document discusses using Bluetooth connectivity and Internet of Things (IoT) technology in smart buildings. It describes how IoT works by collecting data from sensors, storing and analyzing the data in the cloud, and displaying insights. The main goals of a proposed smart campus solution are improving building efficiency, optimizing classroom scheduling, and providing personalized insights to users. The proposed solution would use Bluetooth sensors and an Azure cloud architecture to collect and analyze real-time sensor data on factors like temperature, humidity, light, motion and sound to predict busy classrooms and integrate with building systems.
