Notehello guys
I'm electrotonic student I have little experience MCU PIC 12, 16. and Love MCU code write and share for everyone. Thanks for help.

My plan was to remove completely the indoor tablet and collect directly the data from sensors.
The real reason is that information I need are not the one displayed on the tablet (typically max and min wind speed, average wind speed over a period of time, distribution of wind direction, etc...).
I'm a windsurfer/windfoiler and this is information I'm checking remotely before any trip to sea side.
I know this could be perceived as luxurious, but it is part of the fun side of the game :-)
OH

Yeah I see. Your idea to use an Arduino sounds quite right for your use. You can get a lot of  433MHz modules for the Arduino, with code examples. And also if you want more shall we say realtime collection of data. Using a PC could be quite impractical. It is better to use some cheap module (like an Arduiono/ Raspberry Pi) for the collection of data. And just hook up the PC when needed. One thing you should perhaps look into is the memory capacity(RAM). Depending on how much data you need to store. It could be that an Arduino is somewhat limited regarding RAM capacity. Say you want store data every minute for 24 hours. 24*60 is 1440. And I will guess 16 bit is is needed for temperature and wind speed. That will say you need 4*1440 at least 5760 bytes of RAM at least. It could be that that a Raspberry Pi 4 or Raspberry Pi Zero module would be better choice. As those have more RAM and a SD card reader included.

LinkCAD is a translator / viewer for various CAD formats.

  • Display the loaded drawings in the built-in CAD viewer, measure distances and highlight broken polylines.
  • Use several tools to merge overlapping polygons, join adjacent wires, auto-detect holes and perform many other operations.
  • Correct common design problems, such as open or self-intersecting polygons.
  • Convert several files without user intervention in batch mode.
  • Integrate LinkCAD in your workflow by running it from the command line and customizing the user interface.
  • Fix damaged files, which cannot be read by other software.



I've included the latest version (9.10.1) which runs on Windows/64bit. It also runs fine in linux under wine64.
You may also use two quite old versions for Windows/32bit and native Linux/32bit (they don't support the linux platform anymore).
Just install and run.

Titi, Sideshow Bob, and Devetka, this is changing the original approach I was thinking about.
Based on what I have seen in above posts, it looks like I can gather data from anemometer using an Arduino, store values and publish them on the web.
Still some job to be done, but I now foresee a way to do it.
Just looking for some spare time, as probably most of us  Grin
OH
Would it not be more easy to download data from the indoor tablet unit to a PC. Using the serial link built into the tablet module. Not that it is wrong in any way to do what you plan to do.
