Abstract: This study presents the design and implementation of an automatic room heater control system. An automatic room heater control system is a self-regulating temperature system which uses a set point or value to maintain the temperature of a room. This system allows the user to set a desired temperature which is then compared to the room temperature measured by a temperature sensor and with the help of a microcontroller, the system responds by turning on any of the two loads (cooler or a heater) automatically depending on the temperature difference. The cooler is triggered on when the room temperature is higher than the set temperature and the heater is triggered on when the room temperature is lower than the set temperature. The system was designed and simulated using Proteus 8, a circuit building software used for building electronics system. For coding the PIC microcontroller, micro-c compiler was used. A 5 V DC power supply was designed in order to provide a biasing voltage to most of the active devices used in the system design circuit. The DC power supply was designed and simulated using Multisim software. For testing and simulation of the circuit design in Proteus, the micro-c hex file was loaded on the Proteus schematic design. The system was simulated and working according to the design specifications.
