  4. Testing the LM35 is pretty easy, just connect the left pin to 4V to 30V power supply (Four AA batteries work great) and the right pin to ground (assuming the flat side of the sensor is facing you). Now connect your multimeter in DC voltage mode to ground and the middle pin. At the room temperature (25°C), the voltage should be about 0.25V.
