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

Project Parts

Board

Arduino MKR Fox 1200 https://store.arduino.cc/arduino-mkrfox1200

Sensors

  • Humidity and Humidity: DHT 22
  • Pressure: BPM 180

Data Encoding

3 x 4 ASCII Characters

  1. Humidity in form ABCD which converts to ABC,D % relative humidity
  2. Pressure in form ABCD which conerts to ABC,D hPA
  3. Dust density in form ABCD which converts to ABC,D mg/m³ density of P10 dust
