Wireless Communication for Long Distance Measurement

In the previous chapter, I introduced a remotely powered Arduino sensor platform that used batteries and solar panels. It included a real-time clock that allows the Arduino to go to sleep between measurement intervals in order to conserve as much power as possible.

I pointed out that while shopping around for Arduinos for the project that you should consider the future goal of transmitting the collected data over a wireless connection. Chances are, if you need batteries and solar power to keep your sensor running, you don't have wires to communicate. If you had, you could simply provide power and communications over the same cable. Therefore, I suggested several ...
