This is an option. It's pretty expensive, but it is super accurate <https://davidburchnavigation.blogspot.com/2019/08/exciting-new-barometer-for-navigators.html>: 0.2 mbar across 990 to 1040 mbar. I have one and like it a lot.
I've written a weewx service for reading XDR pressure data <https://github.com/tkeffer/weewx-nmea-xdr>. https://www.dracal.com/store/products/usb_bar20_n/index.php [image: image.png] On Fri, Dec 27, 2019 at 2:01 PM p q <peterquinn...@gmail.com> wrote: > Or buy a pressure sensor and hook it up to your computer directly. > > On Fri, Dec 27, 2019 at 12:36 PM galfert <galf...@gmail.com> wrote: > >> Correct.
