In Engineering Colleges (or in any college) generally there is a bell which rings in the entire campus to indicate the start and end of periods. Such bells have to be loud enough to be audible in the entire campus due to which may times it creates disturbance for the people in the surrounding areas.
To avoid this disturbance We need an Period bell Android Application to be present in the mobile of every staff/management of the campus which will ring a bell as per the periods.
There are cases where the time table slots are different for different classes hence there should be a provision to feed the time table in the app of that specific user and his bell will ring as per his time-table.
The bell should ring only if the student is in the campus I.e. his location should be traced and then decision should be taken.
