Monitoring in the Internet-of-Things

Supervised by A.Simons

Abstract

The Internet of Things ( IoT ) looks forward to a future in which everyday objects are imbued with some processing power and ability to communicate. Networks are created from small devices, appliances or sensors, which communicate via short-range radio. This project investigates and prototypes a domestic surveillance system for detecting the presence of people in the home as an example of what the IoT  may achieve. The idea is that this system will perform remote monitoring of your home while you are away, and will alert you the presence of intruders,

The prototype uses a wide-angle pyroelectric infrared sensor to detect the motion of the human body in a given space. The ZigBee  CC2530 board connected with the sensor communicates via short-range radio to detect the motion of human, using the ZigBee  protocol because of its low power consumption. The connected computer is able to record data about intrusion events and issue a timely alarm  by receiving the monitoring data. The control software was written in C# and provides a user interface for starting and stopping the system, and for reviewing the history of intrusion events.
