Abstract
Conference Title: 2018 21st Saudi Computer Society National Computer Conference (NCC) Conference Start Date: 2018, April 25 Conference End Date: 2018, April 26 Conference Location: Riyadh, Saudi Arabia In current era the Internet of Things (IoT) is becoming an important part of our daily life. It is employed in a variety of applications like smart cities, smart agriculture, smart wearables etc. The aim of this project is to use the IoT with an intelligent event-driven system in order to devise an effective quasi real-time attendance tracker. The idea is to keep the whole system in the standby mode except for the low power motion sensor. On the detection of an event, when a person enters and originates a motion, the front-end embedded processor is alarmed. Later on, it activates the remaining system modules like webcam, communication block, etc. The event-driven feature improves the system performance in terms of resources utilization and power consumption compared to the counter classical ones. A firstsystem implementation is realized and successfully tested. It is based on the raspberry pi 3 board, which is integrated with two Passive Infrared (PIR) sensors andtwo webcams. On the occurrence of an event the webcam is activated and it captures a picture. The picture is registered via the Raspberry Pi webcam server and isshared with other system modules via the Porta Space application, which acts as a hub between the Raspberry Pi and the cloud. Simultaneously the attendance statusis updated via the IFTTT on the cloud-based log. Moreover, the concerned authorities are notified via an email. The process is repeated every time when a person enters or leaves the concerned place. The attendance log remains globally available via the cloud and can be accessed anytime. The system design flow is described. Its parameters are adjusted in order to achieve the effective performance. The proposed system operation is tested with an experimental setup. Results have confirmed proper system functionality.
