I need a raspberry pi that can monitor parking spots so I know if I have a spot waiting for me when I get off of work. Of course I don't know how to code so it will probably never happen.

edit: I meant parking spaces outside of my apartment.

You at least need a drone with camera for it. You would need to implement some object recognition on the images transmitted by the drone

Wut. The parking spaces are viewable by my apartment window.

Point a camera at the spots when unoccupied.Specify the spots exact coordinates to the camera. Set color as baseline. If the color changes by 50% or more, they are occupied. Send alert when all occupied, or when not all occupied.

Now, learn to code it.

The challenge, of course, is snow.

Also: clouds, nighttime, people walking across the lot, and any other color changes that aren't related to other vehicles being parked in the spots.

Plug in a webcam, and upload a photo to a server every minute or so. Or put the Pi online.

Humans are still better at parking spot recognition than $35 hardware.

Of course you'll need a camera with a time machine so you know the spot will be free when you arrive, and not just when you set out.

IFTTT api to create geo fence on my route home to poll the Pi "are there spaces left?" with an email or response yes or no with a photo at the current time.
