Fig. 1 shows a photograph of the proposed data acquisition system. The system consists of four main parts; the master control board, the Arduino board, the power supply unit and the sensors terminals unit. The Master control board is responsible for controlling and monitoring the data acquisition system by using 4 press buttons and an LCD screen. The Arduino board is responsible of measuring the sensors voltages and storing their values in the SD card. The power supply circuit is designated to provide the appropriate voltages to the whole system. Finally, the sensors terminal unit is designed to ease the connection between the sensors and the Arduino board as shown in the same figure.
