DS18B20 Temperature Sensor

Hello,

Anyone know if the probe used by the DS18B20 Temperature Sensor is a thermistor or thermocouple? The probe picture is attached and the link if required is:

Neither, it's DIGITAL, install the Dallas Temperature library from the library manager, there are several example programs therein. The DS18B20 has to have a 4.7k pullup resistor between the +V and signal wires, do you have that?

Worth getting into the habit of searching "datasheet ", many questions are answered that way
(its what we do all the time!)

One thing its worth pointing out is that these sensors are not guaranteed genuine DS18B20’s as
there are a lot of fakes about, and they are not as waterproof as you might hope (stop working
after some time in my experience and many others).
