When I was looking for temperature sensors to provide input for my ski
wax program, I found an I2C temperature and humidity sensor. Sparkfun
has it on a breakout board: http://www.sparkfun.com/products/9418
I did some experiments earlier with using the BMP085 barometer's
internal

bus length can be 9-12 ft. I would suspect capacitance between the
wires is the major problem so I would look at that as the primary length
limiting factor.

Apart from I2C, perhaps 433MHz equipment is an option? I have been looking
into combining that with my Freerunner (or Phoenux) for home

I've disassembled some 433 MHz power sockets and connected the receiver
and transmitter to an AVR that

How about the protocol or signalling? And would it be easily transferred to
an
Openmoko? (Once it's on USB, does it still matter whether you speak to a PC

an ARM?)
Of course both ARM and x86 work.

Do you know about any documentation for these 433 MHz proprietary
protocols? What about using 802.15.4 or ZigBee?
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

At least my remote controlled power sockets have a well documented
protocol. The documentation is described in both the receiver and
transmitter datasheets.

Hello Om community,
Given that the GTA04 contains an off-the-shelf UMTS module and, if my
understanding is correct, truly off-the-shelf GSM/GPRS/UMTS modems in
the consumer USB stick form factor have been used during the

I think you will find that it is imposible to make data calls to an
