Abstract—This research investigated the producing of electric power generated by the temperature difference below 100 ˚C of thermoelectric effect or cooling devices getting power from direct current and the electromotive force from thermoelectric module. In this research, a testing kit was designed to collect the output of temperature difference on the thermoelectric device, and compared the level of electric power of various modules in 2 different circuits, i.e. serial and parallel. The results of the study showed that the higher the differential temperature, the higher amount of electric power and the electromotive force. Also, the electrical connection of thermoelectric module had an effect on power generating when using 2 modules for each circuit, the serial circuit generated more power than that of the parallel circuit.
