Everyone I hope you’re ready for a solid nerd post. No, it’s not about Game of Thrones…… I don’t watch that shit! Plz

This is a project I have been working with my “best friend” John Schulman. As you may or may not know I have a Vanagon Westfalia. I keep said Vanagon in my subterranean grarage as it needs to be protected from the elements. The problem is the garage gets very damp after a rain storm. I keep a dehumidifier in there running 24-7. The issue is I sometimes forget to emty it. It then shuts off and the water begins to pool up on the floor.

John and I figured this might be a great opportunity to use an Arduino to send me a notification on my phone when the tank for the dehumidifier is full and the unit has shut off. John got to work using a Wifi enabled Feather Board. The board has a water sensor on it. Along with a servo arm that moves when the device is trying to connect to the internet. My end of the project is the 3D printed housing for it so it can be attached to the dehumidifier.

John sent me the board last week and the little bugger worked right out of the box. I spent the weekend testing it and designing a housing. As expected we found a few issues.

  1. The wifi in the house didn’t extend to the gararge. I got a wifi extender and that seemed to do the trick.
  2. The notifications aren’t working constantly. We are using ifttt to run the text messages and it is un-relyable at best.
  3. We will use Pushbullet for the notifications going forward.
  4. We are changing the sensor to a floating water sensor as it is a simpler input method.

It pretty exciting as it is 90% there as a little device. Still some tweaks to make but all in all it been a super fun project!

I will be sending the board back to John for code and wireing updates. I will keep you all posted on the progress.

Thanks John!
