Pocket Guard– IoT-ready, Low-cost Personal Belongings Monitoring

This paper presents the development of a low-cost system for tracking and monitoring personal belongings, using the concept of the Internet of Things. The system is composed of three separate parts: a prototype based on the Arduino platform, connected to Bluetooth, GNSS/GSM and accelerometer modules; an iOS mobile app with a graphical user interface that allows the prototype configuration and monitoring; and, lastly, a server to be the interface between the application and the prototype. Results prove the possibility of implementing an accurate, robust, and low-cost IoT-ready device, which can be used as a tracker for personal belongings.
