Overview
Assembly instructions
Possible Configurations
Option 1: cheap, simple, positive only LM35.
- Install solder jumper
- don't install diode, capacitor, resistors.
Option 2: LM35 with negative temperatures.
- install diode,
- install pullup resistor? 50k
- install pulldown resistor 15k.
- Optional capacitor 100n.
- do not install solder jumper.
Option 3: thermocouple.
- install diode,
- install pullup.
- do not install pulldown.
- do not install solder jumper.
Diodes: PNB7000 or BAS31S or BAV99. should all work. Others should work too. The idea is that at 0.1mA forward current the voltage drop is about 1V.
