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.

Project Parts

Data Encoding

3 x 4 ASCII Characters

  1. Humidity in form ABCD which converts to ABC,D % relative humidity
  2. Temperature in form ABCD which conerts to BC,D °C A=0 is a positive and A=1 a negative Value
  3. Dust density in form ABCD which converts to ABC,D mg/m³ density of dust
