What connector you use will depend on how you have your 1-Wire Network setup. Some 1-Wire Interfaces/adapters have RJ45 connectors and some have RJ11. Plan ahead and wire your 1-Wire network accordingly. I have wired my house with CAT5e and some of these Cables are dedicated to 1-Wire. I have also repurposed the houses old phone wiring to 1-wire. Therefore I have a mixture of RJ45 and RJ11 wiring but my sensors are all RJ11 as an RJ11 plug fits in an RJ45 socket and my 1-wire adapter uses the centre two wires. | What connector you use will depend on how you have your 1-Wire Network setup.

Manufacturers Description
"The DS18S20 digital thermometer provides 9-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20 communicates over a 1-Wire® bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18S20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.
Each DS18S20 has a unique 64-bit serial code, which allows multiple DS18S20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18S20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems."
