Design of Smart and Intelligent Power Saving System for Indian Universities
Smart Innovation, Systems and Technologies, 2016
Now-a-days power management plays a vital role in reducing the consumption and efficient utilization of the resource. In traditional system, manual operation of electrical devices in university gets unnoticed, that leads to maximum wastage of power i.e., with different device operating even when the classroom is abandoned. These extended hours of operation leads to maximum power wastage. In order to overcome this problem, we have designed a "smart and intelligent power saving system for Indian Universities", where every classroom is equipped with passive infrared sensor (PIR) which responds to occupancy, and corresponding devices are switched ON /OFF automatically. The entire system is monitored and controlled by the central base station.

MODERN HOME AUTOMATION SYSTEM FOR ENERGY CONSERVATION
Digital Signal and Image Proecessing
Last decade has seen serious concerns for the future availability of electrical energy due to the drastic depletion of the conventional fuel resources. Various solutions have been proposed and implemented, of which, using the available energy in the most efficient manner has been seen to give great results in energy conservation. This project contributes to the efforts of energy conservation with the help of cost effective embedded automation. The system offers two modes, one automatic, and the other manual. The former automates the electrical systems of the home to a large extent using the outputs of various sensors through a control mechanism using PIC microcontroller 16F877A, keeping the energy conservation as its primary concern, while the latter is a more of a conventional system, giving the user certain new perks of the existing technology like controlling the electrical appliances, fans and lighting systems through Infrared Remote Control. The system is accompanied with the technology of The Global System for Mobile communication (GSM).
Automated energy saving and safety system
2014 International Conference on Electrical Engineering and Information & Communication Technology, 2014
This paper reports on a system that can save electricity. Many times we leave the room and hall without switching off lights and fans, thus electricity is wasted. In this work we have presented a system in which energy will be saved based on number of people entering in or leaving out of the room. If there is no person in the room, then light and fan will be switched OFF. On the other hand as soon as any person enters the room, light and fan will be switched ON. On the basis of the intensity of sunlight we can increase or decrease the intensity of light. Simultaneously we can vary the speed of the fan sensing the room temperature. The more temperature the more speed of the fan. A smoke sensor module is used for detecting any smoke within the room and provides safety by alarming the audio device.

Public campus has a mandate to saving of electrical energy. Electrical energy consumption is often wasteful in building. There is tendency wasteful by user. Electronic equipment is often still turn on at idle time. Only a few students want to turn off the equipment and shut down the computer. Saving of electrical energy is not only at idle time but it can be improved into operational hour. It is not depending on idle time or operational hours, but depends on human presence. Implementation of electrical energy saving has to be supported by frugal behavior and equipment technology. In this study, we name system of smart detection and control to electrical energy (Sisdece). This system is consist of hardware and software. Hardware applies passive infrared sensor (PIR) sensor, wireless sensor network (WSN), microcontroller ESP32, access point, relay. Software use C++, hypertext preprocessor (PHP), hypertext markup language (HTML) and android studio. Result of measurement has been done in a month during November 2020. Average of energy saved is 12.51 kWh and total of electrical energy is 105.86 kWh. Comparison of energy saved to electrical energy is 11.81%. This is a significant reduction to electrical bill. The result is expected as benchmark of electrical energy management in Politeknik Negeri Medan (POLMED).

There is need to understand those area and to innovate mechanism to short it out. Negligence has its significant contribution in terms of above mentioned problem. Libraries and institutions are the frequently visited places where the use of the electricity is much important to give the proper illumination and the comfort to the visitor, on the contrary the traditional use of mechanical switches adds on more power loss because of the ignorance. To overcome this power loss and maintain the proper illumination and comfort facility, a new algorithm has been developed as an intelligent Smart Automatic Energy Saving system with an LCD display using PIC16F72 which will first check the entry of a person to the room using PIR sensor, monitoring the room temperature and illumination of the room and based on this the illumination of the light and adjusting the speed of the fan to provide better comfort and environment for the reader and will save the over use of power by shutting down the complete system in the absence of individual in the room.
Design of Microcontroller based Automated Power Saving System for Classrooms
Present scenario of energy crisis not only demands to increase generation of energy but also to utilize it as per legitimate requirement to conserve at public places like educational institutes, where the users are more and no one cares to switch OFF appliances when not required. The aim of this project is to design cost effective automated system which can be easily incorporated in academic institution especially in the class rooms to conserve the energy. Lights and fans switched ON and OFF as per requirement for number of students entered in the class room through person counting subsystem. The implementation is made simpler by using sensor to detect person and compact circuitry built around 8051 microcontroller programs. Through this system, the author wishes to inculcate discipline in the students by giving no option but to occupy the front row first and so on and back benchers to come in front and then only have the comfort of light and fan and at the same time want to help academic institutes to save money on their power bills and contribute in reducing the emission of green house gases in environment.
An Intelligent Energy Management System for Educational Buildings
International Journal of Distributed Sensor Networks, 2013
There is a wide variation in the energy consumption between different educational institutions due to the adoption of different management strategies and different levels of occupants' environmental understanding. The presence of large amounts of information and communication technology (ICT) equipment and heating, ventilation, and air conditioning (HVAC) system causes a major consumption of energy in higher education institution (HEI) buildings. The main objective of this research is to investigate the use of ICT to optimize the energy consumption in HEI buildings and reduce carbon dioxide (CO 2) emission. The first phase of the system has been implemented at King Saud University to measure energy consumption through sensors that read energy consumption of electrical appliances and devices every 10 seconds. The analysis of collected data allows us to develop and employ energy saving strategies that lead to a reduction in total energy consumption. Our preliminary results show that up to 17% of energy consumption can be reduced by simply dealing with standby energy loss of labs' computers. The novelty of this research comes from the use of a functional database approach to deal with high volume of data and query performance and the incorporation of a timetabling system in energy management system.
IJERT-Arduino Based Automated Energy Saver in it and Domestic Load
International Journal of Engineering Research and Technology (IJERT), 2019

This proposed word presents a solution to detect and cutoff the phantom loads both in IT and domestic environment. In this paper, socket supplies the appliances with power when the user turns them on. When the user turns them off, our socket shuts the electric power off and reduces the standby power to zero. In this design, which uses Arduino, receives signals from a Passive Infrared (PIR) sensor which detects the user approaching the socket in domestic environment. A relay panel provides an Arduino to control the relay On/Off when used as an appliance switch for shutting off the standby power. The Arduino monitoring program provides both automatic detection of the user by the PIR sensor and detection of power consumption.
