The circuit measures the car water temperature. CA3161 is a counter and 7segment driver to display amount of temperature on 7segments. The temperature sensor is a diode, 1N4148. This is set near of the Car Radiator. To obtain the 5 V power supply from Car Battery, you can use a LM7805, +5V low cost voltage regulator.
