IoT Beacon-Based System for Buildings: Monitoring and Alerting

■  Project Introduction

▣ This project is part of the IITP Summer Program, and Korean universities & Purdue university participated together.
▣ The members consist of 6 Pusan National University students and 1 Purdue University student.
▣ This project's goal is to improve the problems of previous disaster prevention systems using IoT technology.

It has the following advantages:

1. Accurate information collection and secure information reliability through a separate network.

• It has a wider sensing distance than Bluetooth.
• Detailed location information can be identified.

2. A low unit price compared to previous communication technology.

• It can be maintained for a long time with low power using Bluetooth Low Energy(BLE)
• It is advantageous for real-time large data processing.

■  Project Differentiation

• Through constant interaction with Beacon, users' information is updated periodically.
• This information is used to control Personnel and to figure out people locate in disaster accidents in real time.
• It is expected to reduce bottlenecks and panics that have increased the scale of disasters.
