One of my far fetched add-ons to this project was to make them wireless and create a mesh network so multiple units could be put on a site and give weather profiles to be used in micro weather forecasting.
Mesh networks are complicated, and tend to consume much more power than a simple remote device to central controller approach. This would be a problem if the remote devices were battery operated, but the ultrasonic circuitry may preclude that anyway.
I have just received some cheap RF modules to experiment with, the high power version claims to be capable of 1000M line of sight and costs about £12, that should be more than enough range. When my bus pirate arrives from China I will see how good they actually are!
