Arduino Sigfox Weather

Weather and Dust Values send to Sigfox Backend in an 15 Minute intervall.

Because of a bug, the LowPower.sleep() just works if the programmer is unset, so after programming the arduino, unplug the usb and plug it in again.

yet the 5V just works with USB or regulated external power via vin, so no batteries
