Can't really share any useful link at the moment, but I’ve been working on a solution based on the C1001 mmWave sensor. It collects telemetry throughout the night, including respiratory rate, heart rate (BPM), number of turnovers, apnea detection, and overall sleep quality - you just need to hang it around the bed. The data is sent to a server, which generates a nightly report and passes it to an LLM for analysis.

I've decided to do it simply because of my grandmother: she dislikes bracelets and smartwatches because they’re uncomfortable and she often forgets to wear them. A contactless device could be much more practical for her and for many people like her.
