The thermoelectric known as peltier uses the theory of peltier effect to produce heat difference from an electrical voltage. Peltier is a semiconductor which consists of two ceramic plates with p- and n-type semiconductor material (bismuth telluride) between the plates. The project also uses a 28/40- Pin 8-bit microcontroller (PIC16F877) to control the voltage controller and the LCD screen to display the temperature. Experiment conducted on the pel tier shows that the surface temperature of the peltier can reach a temperature of 14.4 °C by applying 8 volt to the peltier. After 500 seconds, the temperature can reach a low temperature of 1 0.6°C. By implementing basic heat transfer theory which includes conduction heat, convection heat and radiation heat to insulate the heat; a working prototype was built. The inner box temperature dropped from 26°C to 13°C. Although the LCD screen displays a temperature of l3°C from the reading of the temperature sensor (LM335DZ), it is important to take into consideration that the efficiency of the temperature sensor is very low (15.8%) and the error rate is considerably high (16.3%).
