A DIY barograph based on an Arduino shield

Hi,

I just want to share the result of some winter working days to build my own barograph.
The total cost is arround 60 euros and it displays the history of the pressure for diffrent time scale : 3, 6, 12, 24, 48, 72, 96 and 120 hours.
Also, this barograph will alert the sailor if the pressure is droping faster than 140Pa/hour.
The system uses a small screen to display the precious informations.
I hope you will build it for you !
Here is the project :
A barograph for ArbutusUn barographe pour Arbutus | Arbutus

Bon vent,

Paul

Becoming from you, I'm glad ! I used your software for a while, until my anemometer broke. I fixed it this winter though.
NavmonPC is a nice software, thank you to share it !

I appreciate you taking the time to post/document this on your site. Will be fun to play around with later.

Re: A DIY barograph based on an Arduino shield

I know that this is an old thread, but I hope that there is someone how have built this unit and used it.
Have it been useful with the digits of the pressure change during the last ½ hour?
Is there more use of the 1-hour digit?
Is there any use at all of the digits? Do not the graph tells enough?
Have you ever used the graph for 24 ore more hours?
The alarm for pressure drop is fixed to 140 Pa/h. Hade it been better if it was adjustable?
My questions are because I am about to built a barograph without the graph and only show some figures. But what figures?
