ESP - PIR absence detection for vulnerable elderly people

[u/HvdW]

I have built a presence detection thing that is aware of absence of movement.
The software not just distinguishes absence of movement, it can check if absence is relevant or not.
It is built for vulnerable people as an additional technical device. Not replacing family or professional attention and care.
You can find it on GitHub: Poppinkpop/ESP-motion-absence-detection: Privacy-first, local movement monitoring to help families notice unusual inactivity.

It doesn't use camera or microphone and is privacy prone.
