A Smart Classroom of Wireless Sensor Networks for Students Time Attendance System

Today, Wireless Sensor Networks (WSNs) have been included in many researches to form smart environments. IoT is becoming increasingly integrated in our daily life at homes, streets, schools and everywhere. Using IoT based on WSNs in the educational filed is an important resource for better preparing students for the future digital world. Digital students attendance system in schools or universities is an example for case that technology can facilitate the traditional ways for checking students attendance instead of using the manual paper sheets which consume time and resources with higher probability of failure. In literature, there are many time attendance systems that proposed to enhance the manual traditional methods for taking and calculating students attendance in smart ways. In this paper, we proposed a user friendly students time attendance system that can be applicable in different schools or universities in order to form a smart classroom based on WSNs and IoT technologies. We proposed intelligent chairs that can be identified as the sources of information, which integrated with four 50 kg load sensors and HX711 amplifier that measure the students weights and send the digital signals to a receiver in order to recognize the student presence during class schedule. This smart classroom is also installed with one ZKTeco ZK4500 fingerprint reader in order to increase the identification for students. The transmitted signals from the intelligent chairs will be connected by Android application which will be installed on the lecturers' smart phones. So, teachers will get details and summary report of students attendance through the Android app. We implemented our proposed idea using java language, database and android system.
