HackTip How to use a diode as a temperature sensor YouTube
Step 1: Circuit Diagram. As you can see in the schematic it's very simple. by connecting the diode in series with a current limiting resistor and a stable voltage source we can obtain a crude constant current source, so the measured voltage across the diode will only vary due to the temperature change. Make sure that the resistor value isn't.
