The range is probably somewhere around 100ft. As for budget, I was hoping to keep the components of the prototype below $200. Since I'm probably not going to use a GPS module on the prototype, that'll save a hefty chunk of that budget.

Thanks for that. Clearly FM isn't a good choice for cars given the possibility of interference. Cellular seems a bit expensive for the units themselves. Any suggestions beyond ZigBee/XBee?

Also, any suggestions on programming the accelerometer data to be logged/converted from voltage to G ratings after it is transmitted to the computer? Clearly I'm not going to ask for a length of code for that or the XBee protocols, but hey, I'm not going to say no if it shows up.

Well as far as prototypes are concerned, I'm thinking of sticking to using a laptop connected to the XBee explorer as the receiving unit just for proof of concept.

Any board suggestions beyond the Uno?

Is ZigBee a better choice for this over Bluetooth given the power requirements?

I'm curious if it is possible/relatively simple to do the following: connect a 3-axis accelerometer (attached to a Arduino board, say the Uno R3) wirelessly to another board or computer?

I was thinking about using an Uno R3 with an ADXL345 (or similar accelerometer) with the XBee shield and series 1 module (SparkFun models) on the sending unit. and either the XBee Explorer (with module) for the computer connection, or another microcontroller and XBee shield attached with either flash memory or an SD card as well as a GPS shield (with an EM406 receiver).

The application calls for sending accelerometer data (high-G's) from a specific point in a car to a receiving unit that can store the G loads and GPS position, or transmit it to a computer.

Is programming this possible? If you say yes, anyone want to help out with this project from start to finish? I'll give you a cookie (okay, 2).
