+====== Automatic weather station AWS02A ======
 An autonomous weather station with its own auto-diagnostics. The station is designed to work in remote areas together with other scientific instruments like robotic telescopes or[[cs:programming_tasks| other measurement stations]].

 Apart from these technically still unsolved problems, there are other reasons to design such station - most notably an absence of serious OpenSource-hardware solution for meteorological data collection providing data for [[http://openweathermap.org/|OpenWeatherMap]] network. (([[http://www.slideshare.net/Dennsy/gisconf-2012|OpenWeatherMap on the Open GIS Conference 2012]]))
+===== Sensor construction =====
+V této verzi stanice bylo ustoupeno od pokusů používat standardní komerční snímače vesměs uzpůsobené k vestavění do konkrétní proprietární meteostanice daného výrobce. Místo toho jsou navrhovány vlastní konstrukce snímačů a jejich zakrytování.
+==== Stevenson Screen ====
+Prvním navrženým snímačem je radiační štít tisknutelný na 3D tiskárně.  Štít je navržen v programu [[cs:tools|OpenSCAD]] a jeho zdrojové soubory jsou v SVN repozitáři MLABu. Výtisk na následujících snímcích je z biodegradabilního [[http://en.wikipedia.org/wiki/Polylactic_acid|materiálu PLA]].

+====== Automatická meteostanice AWS01B ======
+Tato konstrukce využívá meteorologická čidla ze stanice wh1080.  Jejich vyčítání je řešeno Microchip [[cs:pic16f87xtq44|PIC]] MCU. Od této konstrukce je postupně upouštěno z důvodu špatné dostupnosti náhradních mechanických dílů, jejich kvalitě a omezeným možnostem MCU. Ostatní kvalitní v této konstrukci ověřené snímače jsou však přeneseny do následující verze.

 ==== Data recording ====
-Data measured by weather station should be recorded and displayed locally. That is why a program serving the weather station should run either on local computer or directly on weather station processor. In the latter case, the weather station would probably run a web server as well, which could provide local data previews and send them to collection network.

-Our ideal program should be multi-platform with minimal operating requirements and with possibility of sending data to one of the global network of weather stations. The data should be, at the same time, locally backed up and they should be able to combine with data from other stations.
