This digital thermometer circuit diagram uses a common 1N4148 diode as the temperature sensor. The temperature coefficient of the diode, -2 mV/°C is exploited for this application to create an ...

[rawe]’s simplification of this is to get rid of the transistors and just plop a single 1N4148 diode in there ... 1-Wire temperature sensors. Both the circuit and the tool work with the most ...
