PTC/NTC or resitor as sensor?


Smartin

Question

How do I connect a PTC or NTC (thermo resistor) or any other variable resistor? 

Is it the same as a 2wire sensor?

I think you can't use PTC and NTC sensors because they are passive sensors, DS sensors and DHT sensors have a serial interface to read the measurements
