A data acquisition system as a thermoelectric (TEC) module based on arduino has been developed. I consisted of an arduino module, a conditioning of sensor signal, three temperature sensors of LM35DZ type, a H-Bridge driver, a sample holder, a voltage regulator and a Peltier device of TEC 12704 type. The H-Bridge driver was used to control electric power in TEC module using fast Pulse Width Modulation (PWM) signal at a frequency of 1.95 kHz. The three LM35DZ sensors were used to measure automatically temperature of ambient, hot and cold sides of the Peltier module, respectively. As a result, the module was able to generate temperature difference between two sides of TEC module. The measured parameters using this TEC module included temperature difference, current, and voltage. It was also found that sensor sensitivity and the resistance of internal module of TEC around (10.08 ± 0.26) mV/?C and (3.92 ± 0.01) ? , respectively.
