System Design
From now on, we are going to discuss all the design stages that we have being through from the idea of automation of the IIUM Smart Room system to the last refined design, and determination of components needed, so as to deliver as much knowledge and understanding of the system as possible.



Conceptual Design
The automation of the system will be mainly to control the lights and fans inside the room according to the availability of human inside that particular room. In order to achieve that, we need to determine whether the sensor can synchronize with the electrical facilities place in the room. Not only that, we would also want to determine if we can link the circuit with the projector only for front lamp thus if the projector is on the front lamp will automatically off. Then after all the people left the room (the sensor will count the number of people living the room equal the number of people enter the room) hence the electrical facility will turn off. All the sensor will be set up by count up and count down.

Base on Ohm law theory (V=IR), current will be the same for series circuitry and for parallel circuitry the voltage will all be the same. For our design we will concentrate more on parallel circuitry.
