Design and development of an automatic switch to reduce electric usage in lecture room / Ahmad Zakwan Abd Latiff

The purpose of this study is to investigate the current wastage in UiTM Pulau Pinang and to design a device that can reduce the wastage of electricity in UiTM Pulau Pinang because of a too high electricity bill. The lecture room in BKBA building is taken as a sample because it is likely one of the m...

The lecture room in BKBA building is taken as a sample because it is likely one of the main causes of wastage when the air conditioner and lighting are on when the room is empty.

From the observation, its shows that the total of wastage in 1st-floor lecture room is 24 hours in a week (252 lecture hours) equal amounting to 9.52% from the scheduled class. This is equal to 49.896 kWh total wastage in a week. An automatic switch is design and developed to reduce this wastage. The circuit was electronically controlled using Arduino Nano that will set the timer for 1 or 2 hours when using the lecture room.

As a conclusion, an automatic switch can reduce the wastage of electricity in UiTM especially in the lecture room. It also can reduce the total electricity expenditure. 2017-01 Student Project NonPeerReviewed text en http://ir.uitm.edu.my/id/eprint/35025/1/35025.pdf Abd Latiff, Ahmad Zakwan (2017) Design and development of an automatic switch to reduce electric usage in lecture room / Ahmad Zakwan Abd Latiff.
