DHT22 Temperature/Humidity Sensor

Schematic

Technology in the Appalachian Foothills: DHT22 Temperature/Humidity Sensor.

Here’s a little something I cobbled together from a DHT22 Sensor, an Adafruit DC BoArduino, and a 3-digit LED display. More to come!

  1. Thanks for sharing your project!

  2. You’re welcome, Marty! This, like all of my projects, was just too much fun to keep to myself!

    And thanks to The Lady for posting it!

  3. Oh, by the way…

    The hand-sketches… yeah, I know. I can’t help it- you see, I’m OLD, and this is the way I used to do things with my colleagues, Pre-PC.

    Actually, that’s not really true- I can help it- in fact, I used AutoCAD for years, and I was a real whiz at OrCAD back in the day…

    So, here is a request to all of you nice folks out there to help an old man out. What say?

    I’ve been looking at Eagle and KiCAD, trying to decide which one is worth the investment of my time. Right now, KiCAD is coming out ahead, despite the tremendous popularity of Eagle. I like KiCAD because there is no board size limit, and the footprints aren’t tied to the part numbers (being somewhat anal, I like to design my own, thank you very much!)

    So- I’m prolly gonna go for KiCAD. I’m interested in hearing from users out there- pro and con.
    Thanks!!

    (CAD or not, I’ll NEVER give up my quadrille-ruled Lab Notebooks!)

  4. I so was going to share this too. :D

  5. kgroce-
    I sincerely hope that you do share your project. I would be frankly astonished if our designs turn out to be identical.
    Looking forward to learning something new from your solution.
