Power Saving for Lecture Room in Universities

Abstract

Power saving is a reduction in the amount of energy consumed in a process or system or by an organization or society, through economy and rational use. Power consumption become one of the problems in Sudan due to the high rate of KW that vary in price depending on the usage, in universities and educational institutes the consumption of power become a problem due to the high power usage daily within the working hours or on the break time, that affect the overall budget. The aim of the thesis is to reduce power consumption by designing and implementing power monitoring and control circuit to reduce the power consumption in lecture room. The circuit uses wireless link between the class room and the power mains, while the Radio Frequency Identification (RFID) tag of the lecture is identified. Passive RFID module was used to detect the RFID tag and transmit it to the receiver in order to switch ON/OFF the class room appliances and start counting to the end of the lecture time in order to switch off.
