Do you know about any documentation for these 433 MHz proprietary
protocols? What about using 802.15.4 or ZigBee?<br>
I want to use Freescale MC13233C [1] in my indoor/outdoor
temperature and humidity monitoring project. Please tell me, if you
know about cheaper 802.15.4/ZigBee modul or about any free samples
from semiconductor manufacturers.<br>

an option? I have been looking into combining that with my
Freerunner (or Phoenux) for home automation. </p>

quite cheap as long as you don't need USB (or other generally
available) connection. Many of them use the same chips and for
Arduino there's a library [1] available to read temp and
humidity.</p>

to your Freerunner of course (and you'd need an Arduino).</p>
