Automatic Bell Ringing with Energy saver and Notice Announcement Energy is the most important factor now a days , and also the conservation of energy is important because of the short fall.
Simple and General Block Diagram Today due to the short we are facing the problem of light cutoff, with exists from 2 hours minimum to maximum of 8 hours. Due to this cutoff lot many industries and domestic life is getting disturbed , industry because of the reduction in production and domestic life due to not sufficient supply.
Since we are going be electronics engineer , and as a part of partial fulfillment of the requirement by MSBTE we have to submit the project , this is over first step in thinking of conserving the energy.This Prototype model is demonstrating the same.
Considering the row as the benches of the college class room and light and fan are fitted as shown in the layout
Now let 5 students are sitting on one bench.When one student is entring the class room the light and fan of the first row will be on till student count is 5 , as soon as 6th student enters the classroom next set of light and fan will be on and so on. Same will the sequence of the light and fan will be swtiched off.
Mainly two sensors are used , one for counting the incoming student and other for counting out going student.
When a student /person cross the incoming sensor are count is increased and checked for the limit and depening upon the count range from 1-5 , 5-10 and so on lights are turned on.
When a student /person cross the outcoming sensor are count is decreased and checked for the limit and depening upon the count range from 1-5 , 5-10 and so on lights are turned off.
Hence when the count is zero , minimum needed light and
