    The last 24hours of readings is a very useful feature to have when you share a house with people who insist on resetting the needle every time they pass the barometer ! A variation may be to use an e-paper…

    Very nice build and video. I was most impressed by the library you wrote for the pressure sensor. At the moment, writing a library is way above my pay grade!! Neil

    Hi Katie,

     

    Thank you very much for this nice project.

    Thanks. I hadn't done pressure before either, likewise only projects with humidity and temperature.
    Using a chopping board is a great idea for backings, and the lamp project sounds intriguing!

    Nice build, not used a pressure sensor yet, did humidity and temperature in one project and an RTC in another. I do like I2C and a lot of people complain about it but you seemed to have made light work of that.

    One of my early clock projects re-used a circular chopping board as the back. And I have some IKEA surplus lined up for a lamp project.

    Love the design aesthetic! Anything with blinking lights automatically gets my approval image

     

    Great build, Katie!

    Thanks.
    I used to think it was a bit daunting, but after having to do some changes to an exsisting library at work I got my head around it fairly easily and realised it's not that different to any other code.

    I like the e-paper idea, I've got another project in mind to use a big e-ink display as a home monitor, and adding local information such as temperature and weather would be an interesting addition to that.

    We had a barometer at home when I was growing up, and every time my brothers or I passed it we'd give the needle a little turn! When I got older and interested in how it worked I'd set it every time I passed but by the time I got back I was usually moved again!

    A variation may be to use an e-paper display to try capture some of the essence of the chart recorder barometers.
