Waterproof Temperature Probe (DS18B20)

Hello,

There doesn't seem to be a wiring guide for the Waterproof Temperature Probe (DS18B20) that's sold in the Konnected store. Can someone please help me figure out how to wire this up?

@Support - It would probably be a good idea to either link to the answer on the product page or create a new link in the "How to Wire" section. Some of us require a bit of hand-holding :)

Thanks in Advance!

Ds18b20 - see attachment. Red - 3.3 or 5v - constant power Yellow - Digital - konnected zone of choice Black - Ground - ground Resistor needed when using long wires or multiple sensors. In Smartthings Once wired and configured you will have to wait approx. 3-6mins before the sensor shows up in the things menu with its Id number as its name.

This is an old topic but I have a question. The diagram shows the mentioned resistor but it is labeled as a 4K7 Ohm resistor whicj is obvously a typo. So what is correct? is it a 4K, a 47K.

No typo, some people like to use that format where the k takes the place of the . 4k7 = 4.7k, 4700 Ohms

A spec of dirt on a schematic that's supposed to read 47k gets interpreted as 4.7k could be very problematic

Is that a Europe thing? Worked in Electronics 46 years, Retired now since 2015. Never seen it annotated that way. I still learn something new every day.

Unsure of the origin of this practice but its considered RKM code.
