MVJ College of Engineering students design an attendance tracking system

Taking attendance in schools and colleges and managing the records is often a time-consuming affair. If a class has a strength of 40 to 50 students it might not be an issue to complete the attendance within 5 minutes, but what if the class has 100 students! The teacher may waste a lot of time in taking attendance itself.

Now to fix this, the students of  MVJ College of Engineering have designed a Bluetooth based attendance tracking system called BT Proxy that helps in tracking the student’s attendance mandate.

As students walk into the classroom, the teacher will open an application on his or her smartphone and activate the ‘scan’ button. The app will show a message stating “discovery started”, and will detect all the signals sent out by identity card chips, which have been linked to a University Serial Number.

The low energy Bluetooth modules will be implanted inside the ID card of every student. This module is very small compared to regular Bluetooth module. It also consumes very less power. Each module is powered up by a button battery and can last up to a year. Each module will be given a unique ID, and the ID can only be set/reset by the administrator.

Every class will have an atmega32 module, HC05, Bluetooth module, and a WIFI module. An RTC module will keep track of the time. Class periods, break etc. can be set as required. Once a class starts the module automatically scans for all the Bluetooth IDs and passes on the data to the attendance monitoring application or any other required destination. There won’t be interference with IDs as each id has a unique code.

With such solutions implemented in schools and colleges, the time consumed in taking attendance can be eliminated.
