Temperature controller / Mohamad Nizam Ehsan & Nurul Elina Abdul Rahman

The project aims to design an automatic temperature controller for a closed area such as office room. The temperature of the closed area was controlled by the temperature controller at a certain setting level. The setting of temperature levels are set by the user according to the temperature they want to maintain at the room. Otherwise, the temperature of a closed area is change by the operation of fan or air conditioner. By controlled and maintain the temperature of an area, the problem of heat fluctuation in an electrical equipment especially can be solved. In this project, the cut off temperature level that will switch ON the system is set to 34°C. The system will switch OFF when the temperature of an area is below than 32°C. Proteus 7 software is used to simulate the design circuit. The main component used in the project is PIC microcontroller and temperature sensor LM 35. As a result, the project design was working according to the objective
