Snoop Hogg: Real-time hedgehog detection

May 2025A few days ago

Meet Snoop Hogg, my daughter's African Pygmy hedgehog.

Yo Hogg!

He's a bit camera-shy. I'll try to get a better photo of him soon.

Hedgehogs spend most of their time sleeping. When they do come out, it is usually in the middle of the night, so you don't get to interact with them as frequently as you would, say, a hamster.

To foster more quality time between a girl and her hog, I attached a motion sensor to a Raspberry Pi. Now, when Snoop wanders about, we get a notification on our phones, via a Ntfy instance, announcing his presence.

A second phase was to add the infrared camera, upload the videos to S3, and publish them here on this page. It works, but the camera' field of view is a bit narrow for this use case.

The next steps are to try a camera with a wider-angle lens so we can see more of Snoop, find a better way to mount the camera, and to find the sweet spot with the motion sensor sensitivity to reduce the number of false-positives.
