    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 (1-255).  
    9 After updating RADIO_ID and downloading the code you should be ready to go. 
    108This sensor sleeps most of the time. You can change the sleep interval by updating SLEEP_TIME define at the top of the file.

    27 This is the stuff you need to purchase to build the HumiditySensor. 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. 
    28  
    29 1x Cheap Arduino Nano without serial interface and usb connector\\

    31  
    32 8x Dupont cable Female->Female for radio module (and you might need 3 extra cables for your humidity sensor)\\

    34  
    35 1x NRF24L01+ wireless data transmission module 2.4Ghz\\

     25To build this sensor you'll need one arduino + radio specified in the base kit found here:\\ 
     26http://code.mios.com/trac/mios_arduino-sensor/wiki/WikiStart#Buyingguide\\ 
     27With the following additional parts: 
    3728 
    38291x DHT22 Temperature and Humidity sensor (there also exist a cheaper humidity sensor called DHT11 that is less accurate but half the price).\\

    4031 
    41 1x Pull up resistor (4k7)\\

    43  
    44  
    45 (You might later need some housing and transformer or battery compartment as well) 
    46  
    47 TOTAL SENSOR PRICE: $3,99 + $0.93 + $0,6 + $4,99 = $10,50 
    48  
    49 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. 
    50  
    51 1x Serial to USB adapter to download code to cheap Arduino Nanos\\

     32TOTAL SENSOR PRICE: $7,6 (arduino + radio) + $4,99 (DHT22) = '''$12,6'''
