  SCHOOL TIMER

Ringing a school bell manually or relying on a clunky mechanical timer is decidedly old school. You can use this simple, modern school bell timer circuit instead.

Probably since the time schools came into existence school bells were used in the system, an indispensable piece of equipment for every school.

They are basically a mechanical device that is able to produce a loud and sharp sound under the influence of an external applied force. The function of a school bell has fundamentally remained the same since the beginning – to divide the class periods into equal parts and indicate their start and finish with a distinctive sound.

This type of bell has slowly been replaced by more efficient electric bells and they are in use even today in most schools for the same purpose.

School Timer was designed to meet the needs for an easy programmable school bell timer, to activate electric gong bell or sirens on factory floors to alert shift changes or breaks, or any similar application where an external device needs to be triggered at a specific time on a daily or weekly schedule.

Active T5-40 is microcontroller equipment which can be used for school, colleges and factories for avoiding manual interface for ringing the existing siren or a gang bell.

In many schools the operation of the bells relies on a staff member manually operating a switch each time a school period, lunch or recess bell is required. This device is basically a bell timer, which rings the Electric gong bell at set times for the preset programmed duration as per requirement. This is a cyclic timer which maintains the stored values of time in a built-in memory and repeats the cycle on programmed days at exact programmed times.

Benefits : Plays bells at preset times, No need to assign a person for ringing bell every time, Accuracy to timings, No manual intervention, Saves man power and money, Easy programming with the help of manual.
