Datasheet for the LM35 precision centigrade temperature sensor in a 241 KB PDF. The LM35 delivers an analog output scaled at 10 mV per degree Celsius and runs from a single supply, so it often appears in thermostats, fan controllers and measurement boards. During repair the document helps identify the pinout of TO-92, TO-220 or SO-8 packages, check expected output voltage at room temperature and verify supply range. Measuring the output with a multimeter against the stated scale is a quick way to judge whether the sensor is healthy.
