You can probably just use a cheap motion sensor instead of the webcam if you wanted to. There so many now

- hipjiveguy 8mo agoIf you have some to suggest, I'd love to hear it... TIA!
- dimitri-vs 8mo agoWhat's your budget? https://en.tokyodevices.com/items/128 https://en.tokyodevices.com/items/128 But seriously you can probably DIY something a lot cheaper.
- bayesianbot 8mo agoSomething like LD2410 [0]. IIRC there's newer ones that report accurate position and even heart beat rate, but I've forgotten the names of those.. [0] https://dronebotworkshop.com/ld2410c-human-sensor/ https://dronebotworkshop.com/ld2410c-human-sensor/
- IanCal 8mo agoHere’s one https://thepihut.com/products/60ghz-mmwave-breathing-and-heartbeat-detection-sensor-mr60bha2 https://thepihut.com/products/60ghz-mmwave-breathing-and-hea... Same kind of tech but higher frequency.
- embedding-shape 8mo ago> The MR60BHA2 is a 60GHz wave sensor that detects breathing and heartbeat patterns. Using its radar technology, it can monitor vital signs without direct contact, even through materials like clothing or bedding. You can use it for sleep monitoring, health assessments, and presence detection. This is kind of crazy, I had no idea this was a thing. And here I have PIR sensors all over the place and hacks around those, that definitively sounds much better. Besides being more expensive and weaker range, any drawbacks for using it for motion sensing?
- danielheath 8mo agoFound a few aliexpress sellers offering LD2410C's, but all cost 30% more than the webcam I used.
