Wireless temperature sensor using Olimexino-328, XBee, and DS18B20

I have made temperature sensor in the past, but now I added power saving features to the code.

The result was a device which lasts almost a month when it reports temperature once an hour over XBee and is powered by 1000mAh LiPo battery.

Custom XBee Shield with DS18B20

Instead of official Arduino, I used ...
