Hardware

• Raspberry Pi
• DS18B20 temperature sensor
• RRU 4K7 resistor

Software

• RaspBMC or Raspbian
• Node.js

Drivers

• w1-gpio
• w1-therm

Usage

First, load the drivers

sudo modprobe w1-gpio  
sudo modprobe w1-therm

then determine the device id of your sensor (28-000004e23e98 in my case)

ls /sys/bus/w1/devices/   

open server.js and set the deviceId variable to your device id

var deviceId="28-000004e23e98";
