Smart and Energy Efficient Power Saving System in University Based on Wireless Sensor Network

Abstract

In today's world power management plays a very significant role in reducing the power consumption and the efficient utilization of the available resources. In the traditional system, due to the manual operation of the different electrical appliances in the university gets un-attended, and that leads to the maximum wastage of the resources such that the different appliances operating during off-peak hours without any need or requirement and also the street lights remains burning with full intensity during off-peak hours and zero traffic hours. In order to overcome this problem, we we have designed a "smart and energy efficient power saving system", where every rooms as well as every devices are equipped with passive infrared sensor (PIR) which responds the occupancy, and correspondingly devices are controlled automatically. All the street lights are controlled using real time clock (RTC), and the studies astronomical data from Indian Meterological Department and the traffic is detected using the laser according to which the street lights burns with full intensity during peaks hours and with reduces intensity during off-peak hours. Also, a traffic based switching is incorporated for efficient utilization of resources during off-peak hours. There is a secure wireless data transmission methodology used for data transmission from sink to the base station. The entire system is monitored and controlled by the central base station
