4. INTRODUCTION
Controller based model to count number of persons visiting
particular room .
It receives the signals from the sensors.
Signal is operated under the control of software which is stored
in ROM
All program is monitor by microcontroller AT 89C52
7. WORKING PRINCIPLE
This counter Sensor consist of 3 Section
Detect Object (Sensor)
o Data Processing (CPU)
o Display by LCD /7 SEGMENT module.
o Count number of person enter and exit from room.
11. CAPACITOR
Store energy
Application
Motor starters, Tuned circuits, Sensing, Oscillators, Signal
processing, High-pass and low-pass filters
connections
12. IR TRANSMITER AND RECEIVER
Receiver connect with 5V
Signal comes then outputs is low.
LED is use for transmission.
Operate with 5V.
13. OTHER COMPONENT
Message display in LCD
Flip flop use for two stable state
Crystal is use for electrical signal
15. ADVANTAGES
No need of human intervention.
Can work 24x7 without any problem.
Low cost and very easy to implement
16. CONCLUSION
We just took up this project as we were interested in electronics
and wanted to learn about it. Through this project, we learnt a
lot about the functioning and use of different electronic
components and their applications in real life. We were able to
correlate what we studied in our course to real life.
Also this is very simple and effective idea which can be used in
many places like hostel and hotel rooms to save energy.
Thanks to our faculty for guiding us in this project.
