I've been tracking my sleep quality via a DIY setup. I.e. an ESP32 plus two mattress movement monitoring pads. Each night I start the ESP32 recording the movement data from the 2 pads that are under the mattress. The ESP32 has ADCs to collect the analog measurements and sends the movement data to a debian based SQLite db wirelessly every minute. When I wake up, I register my perceived sleep quality (from 0 to 5). I've been gathering the data for several months and plan to run it through ML/scipy to see what insights I can glean. The setup is very cheap - the mattress pads can be obtained for next to nothing at thrift stores.
