WeatherStation

Code for an Arduino UNO driven weather station, using the Sparkfun Weather Shield

BOM

• Arduino UNO R3 model B (or similar UNO compatible board)
• Sparkfun Weather Shield for Arduino Uno R3

Arduino libraries

• Wire.h
• SparkFunMPL3115A2.h
• SparkFun_Si7021_Breakout_Library.h
• ArduinoJson.h

Introduction

As an Arduino starter I wanted to built my first complete, and usable, project. A weather station seemed to be the next logical thing to do. As I was browsing for ideas I stumbled upon many instructables from others, but most of them kept it basic as in 'reading out data from the sensors'. Thus, not very exiting.

Zambretti

The Zambretti Forecaster is a forecasting tool which we can implement as an algorithm to use with our sensor readings. A Zambretti algorithm will return an index Z indicating a description of short term weather changes. Originally the Zambretti Forecaster was a table joining the descriptions to the alphabet.

The algorithm idea I used as a base was borrowed from fandonov/weatherstation, another Arduino weather station project (with other sensors and bling).
