  • DallasTemperatureSensor

    v13 v14  
    55You can download the Arduino sketch here:\\ 
    66http://code.mios.com/trac/mios_arduino-sensor/browser/trunk/Arduino/DallasTemperatureSensor 
    7  
    8 Before downloading the sketch to the Arduino you need to select a unique RADIO_ID (see top of sketch source code). The RADIO_ID must be unique in your radio network and is also used on the Vera side to distinguish between different sensors.  
    9 After updating RADIO_ID and downloading the code you should be ready to go.

    27 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.

    31  
    32 8x Dupont cable Female->Female (you might need 3 extra depending on how your DS18b20 is hooked up)\\

     24To build this sensor you'll need one arduino + radio specified in the base kit found here: 
     25http://code.mios.com/trac/mios_arduino-sensor/wiki/WikiStart#Buyingguide 
     26With these additional parts: 
    3727 
    38281x Waterproof DS18b20 temperature sensor\\

    4030 
    41 1x Pull up resistor (4k7)\\

    43  
    44 (You might later need some housing and transformer or battery compartment as well) 
    45  
    46 TOTAL SENSOR PRICE: $3,99 + $0.93 + $0,6 + $1.66 +$0.02 = $7,2 
    47  
    48 To download code to the cheapest Arduino Nano sensors (that is missing the serial USB port) you need to buy one of following as well. It is only attached while downloading code and can be reused between sensors. 
    49  
    50 1x Serial to USB adapter to download code to cheap Arduino Nanos\\
