Hi!
I am working on a arduino based "weather station". It features e-Paper display and is based on a combined Adafruit sensor that gives atmospheric pressure, temperature and humidity. the goal is to replaced an old digital termometer/weather station that worked really well for some years but stopped working some time ago.
Disclaimer 1: I know that weather prediction is much much more than showing an icon of a sun or cloud based on simple local measurements. That is why we have satellites, super-computers, sophisticated weather stations, meteo-baloons, etc.
Disclaimer 2: I am fully aware that the public in this forum understands something different under the term "weather station". I just do not know any other name for these:
things: https://www.amazon.com/Ambient-Weather-Wireless-Temperature-Barometer/dp/B00BQFWYF2/ref=sr_1_12?s=furniture&ie=UTF8&qid=1497951888&sr=1-12&keywords=weather+station
Still that little thing that I had (unlike the other two I have at home) worked pretty well as an input for my decision how to get dressed in the morning.
Up to now I understood that basically it is not the current pressure that is interesting for short-time prediction but rather the change in the pressure. And if it goes up the weather should be fine, if it goes down the chances for rain are higher.
What I am looking for is something more specific - algorithm, thresholds, values, parameters. How does all these digital thermometers /weather stations work? The only thing I found online are several sites with "Sager open-source algorithm" , but there is no description and the js source code is not exactly good at explaining the working principle.
So, can someone please point me to some online materials or explain about how to choose what is the coming weather based on the sensors I have?
Thanks!
P.S. If someone is interested in the device I am working on I am happy to share more details.
