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.
