Abstract
The control of electrical appliances including lights, fans etc. is maintained manually in institutions. As part of getting smart in every aspect, why can’t we think of a smart power saver which would control these automatically by itself ?. This project is intended to work as a power saver unit which can be utilized efficiently in institutions. A visitor counter is present at the entry which counts the number of person inside the room. When a person enters a room, the fans and lights get automatically ON. At a zero value in the counter, they get turned OFF. Here power saving can be efficiently implemented by using a centralized control, wherein the complete control of electric devices is done by a central unit. This can be managed by using the emerging technology of internet of things (iot). When a single person is present within the room, the associated devices gets turned ON, not the whole. Similarly, the power will be available to persons based on the count within the room. So, this is a social relevant project which can be implemented without much difficulties, in institutions where a wide area of control is required. The control is managed by the said central unit using web facilities.

I. INTRODUCTION
The modern world has developed in every aspect, including technology and infrastructure. Electronics introduced various technologies to manage our useful time efficiently. Most of us would have come across the situation that when leaving a room, we forget to turn off lights and fans.
In today’s world, there is continuous need for automatic appliances. So, to make things smarter, we need to find ways of power saving equipments. Smart campus power controller is a controller based model to count number of persons visiting a particular room and accordingly light up the room. It also shows present number of persons inside a hall. Providing a centralized control, the project finds to be useful in campuses having number of departments and subdepartments, where electrical equipments are controlled manually. There will be a lot of power wasted. Here, by a centralized control using IoT(Internet of Things),there will be no timelag in switching.
II. CIRCUIT DETAILS
Block Diagram:
Flow Chart:
2) Two IR sensors are present which are used for counting purpose i.e acts as bidirectional counter. 3) Relay switches provides supply to the end device from power supply.
4) If count value = 0, then relay automatically turn off the power supply. 5) The first set of relay is controlled by web page toactivate power to the circuit. 6) The second set of relay is controlled by count value.
7) The third set of relay is controlled by PIR sensor.
8) PIR motion sensor is used to switch ON the fan or light closer to person.
9) The number of visitors entering a room will be displayed on the LCD display and the Website.
The power to circuit is provided by clicking on the TURN ON/TURN OFF button on the web page. After turning on,when a person enters the room, the count value is incremented by the counter and also displayed on the web page. The PIR sensor detects the presence of person and the associated device is switched ON. If TURN OFF button is clicked on the web page irrespective of the presence of person, then there will be no power supply. If TURN ON button is clicked, then it retains previous value ie count value and also associated devices get switched on depending on the presence of person.
III. ANALYSIS
Merits:
1) Utilising power, ie power management. 2) Power saver.
3) Energy conservation. 4) Centralised control. 5) Power automation.
6) Room details ie no of visitors.
Demerits:
1) Does not distinguish between man and Object.
2) Simultaneous entry and exit cannot be accommodated . 3) Un-interrupted internet access.
Applications
1) For visitor counting purposes 2) Automatic Class room power control 3) Power Saver in Labs, Seminar halls
Future Expansions:
1) By using camera module with digital image processing techniques we could make accurate counting without ambiguities of object or human.
2) By modifying this circuit and using two relays we can achieve a task of opening and closing the door.
IV. CONCLUSION
The objective of the project ‘Smart Campus Power Controller’ is to count the number of visitors as well as automatic power control. Also this product finds to be very useful in Energy Conservation and automation in our daily life. Online access can be provided by implementing IoT.
