Dallas Temperature Sensor
Software
You can find the Arduino sketch to download here:
http://code.mios.com/trac/mios_arduino-sensor/browser/trunk/Arduino/DallasTemperatureSensor
Before downloading the sketch. Please select a unique RADIO_ID. The RADIO_ID must be unique in your radio network and is also used on the Vera side to distinguish between different sensors. After updating and downloading the code you should be ready to go.
Wire things up
Follow the instructions in ConnectingRadioModule to connect radio module.
Hardware - Purchase guide
This is the stuff you need to purchase to build the DallasTemperatureSensor. Note that I've provided links to the things I bought during the development. You might find it cheaper somewhere else. Also note that you might need to buy like 10x of some items to get the price specified.
1x Cheap Arduino Nano without serial interface and usb connector

(You might need some housing and transformer or battery compartment as well)
TOTAL SENSOR PRICE: $3,99 + $0.93 + $0,6 + $1.66 = $7,18
To download code to the cheap Arduino sensors you might need to buy one of these as well. It is only attached while donwloading code and can be reused between sensors.
1x Serial to USB adapter to download code to cheap Arduino Nanos
