The XBee will certainly work underwater, however its signal will be attenuated. Obviously the more water, the worse things will get. Any of the 900 MHz XBees should perform better than the 2.4 GHz ones.

And hey if you do test this, please do post your results, we'd all like to know what you found.


There are some relatively simple ways to communicate wirelessly underwater but it gets exponentially more complicated that faster you want to transmit.  For instance, I have heard of people using homemade hydrophones (similar to those used in whale watching) to communicate point to point.  These hydrophones are essentially a water sealed piezo device.  This device can be operated as a transceiver since it can be driven to generate sound waves and then generate a signal when subjected to sound waves. It is pretty straightforward after that to devise some sort of protocol for communication of simple I/o addresses and states for you receiving device.  I'd start by searching for roll-your-own type hydrophones.

Btw, I'm a big freaking nerd for knowing this.
