Arduino Weather station (school project)

Arduino Weather station

I’ve nearly finished first year out of three on HTX, which is a kind of Technical Highschool. On HTX you have a lesson called Technology where you have to find a problem, and then find a way to solve it!

Our last project this year was about the weather, and me and my friend found a problem on the harbours – they don’t know the correct weather where they are. So we chosed to make a weather station.

We ended up using an Arduino Duemilanove connected to a temperature sensor, pressure sensor, rain sensor and wind speed and direction sensor. All these data is shown on a 128×64 GLCD display! Please take a look at this video to see how it ended up working (the things on the display is in danish though)…

 

The shield which is on top of the Arduino is made in Eagle. You can see the schematic here…

The source code can be found on our Github:

Featured in the local newspaper
We were recently (7th March 2012) out placing this weather station on the roof of a local harbour.
In that occasion we were interviewed by the local newspaper and the article (OBS. in danish) can be found here: Weather Station article

IN DANISH
Vi skrev desuden en 40 siders rapport som kan downloades herunder. Desuden lavede vi en salgsbrochure som også kan downloades.

Efter den ovennævnte artikel blev bragt i Dagbladet blev vi desuden ogsÃå fremvist på skolens hjemmesides nyhedssektion: http://htx.ucholstebro.dk/pages/visNyhed.asp?NewsGuid=84579

    I like this 🙂

    One comment though. The temp sensor is surely not measuring to that degree of accuracy even if it is calculated as that. You will no doubt know that if you watch it, it will jump from one specific decimal to another. Maybe it is more appropriate to stick to a no decimal places…

    Other than that it seems like a great project, maybe a little tweaking in the future but all projects require that!

    Obviously you are not in the UK but any ideas about where one might go about purchasing the wind speed cups and other hardware? Any keywords I should be searching for?

    The temp sensor is that accurate! It’s an DS1820 with a accurace of +-0.5 celcius, but the resolution is 12 bits, which means 22 steps pr. degree!
    You can buy the wind and rain sensor as a package from Sparkfun – http://www.sparkfun.com/commerce/product_info.php?products_id=8942

    Fin vejr måler, ville også gerne lave en, som jeg så ville lave i forbindelse med min garage port styring. Dog ender jeg nok med at købe noget billigere, og så modificere det til det jeg skal bruge.

    @bld
    Tak.
    Det er muligt at finde meget billigere mini vejrstationer/målere i byggemarkeder mm., men vores mål var at fremstille et selv, helt fra bundet, uanset omkostninger (betalt af skolen)

    Men jeg ved derimod heller ikke om det er muligt at modificere disse vejrstationer til at sende et signal ved forskellige handlinger 😉
    Men god fornøjelse – jeg vil gerne høre hvordan det gÃ¥r nÃ¥r du nÃ¥r sÃ¥ langt…

    Hi Jody.
    The Arduino sketch can be found on our Github here: https://github.com/TKJElectronics/ArduinoWeatherStation/blob/master/ArduinoWeatherStation.pde

    Det ser sq* godt ud, mester! Endda pænt organiseret pÃ¥ et (hjemmelavet?) shield, og en nydelig kasse oven i købet! 🙂
    Der er bare én ting jeg ikke lige forstÃ¥r… hvorfor viser du 3 forskellige vindretninger i løbet af den korte demo? Skiftede vindretningen sÃ¥ hurtigt, eller var det blot en demonstration af funktionen?

    @Hans Thorsager
    Mange tak 🙂 Ja shield’et er hjemmelavet.
    Grunden til at vindretningen hele tiden skiftede var fordi vi befandt os inde i en gård med en del turbolens, som derved fik vejrhanen til at dreje rundt.

    Har du tilfældigvis stadig print-layoutet liggende?
