lighting system in laboratory at Faculty Kejuruteraan Elektrik (FKE) , Universiti
Teknologi Malaysia always been detected did not turn off most of the night and
caused the increase in electricity bill and energy wasting. So, one of the method can
be use to solve this problem is to apply the counter system for visitor using
microcontroller.
A counter system can be design in many ways such as combination of gate
logic and microcontroller. Gate logic is simple and easy but this feature difficult to
varied and becomes complex if the system needs more improvement in requirements.
But, by the using of microcontroller, a system can be more complex but easy to
design. This system will be installed in a laboratory which focused on the main door.
This laboratory in FKE only use one way to in and out and so that, this system is
suitable for this purpose. A sensor will be use to detect a person enter and out from
the laboratory door and send signal to microcontroller. This microcontroller will
count up and down based on the programming that been embedded on the PIC. A
LCD display will inform the total occupant inside the laboratory and at the same time
will display the counting data when a person enter or leave the room.
1.3 OBJECTIVES
This project is carried out to reduce energy wasting by residents in faculty by
designing a prototype system with simple features. The objective of this project:
i. To design a system that will automatically control the lighting system
ii. To differentiate whether a visitor enter or leave the room and consider the
probabilities using counter system
iii. To display the total visitor present in the laboratory and display the height of
the visitor
