My projects

 I use Raspberry PI 3 (Model B Plus Rev 1.3) to monitor temperature with DS18B20 around the house for few years now. Configuration is simple: I use multiple DS18B20 sensors (currently it is 7) that are connected in parallel with one 4.7kohm pullup resistor between Vdd  (3.3v) and DQ (Data) connectors.  I don't use "parasite power" mode. In my experience 3 wires connection is more reliable. I'm not going to walk you through all setup. There are multiple different manuals in internet and most of them are very detailed.  Couple of days ago I decided to replace Raspberry PI 3 with Raspberry PI Zero W. Raspberry PI Zero W has lower power consumption so I can use regular prone charger instead of special Raspberry PI power supply that provides 2.5A output. Currently I'm using  Samsung Charger that produces 1A. My first thought was "There is no difference between Pi 3 and Zero from configuration perspective. What can be easier, I did it multiple times...
