We’re 17-year-old students.Our heartbeats and breathing information are both indicated on Oled. We can detect that sleep state showing”in bed”.However, the “awake” is unstable. After we detected “in bed”, that report said , we would receive another state in ten minutes.But we tested it ten times, we only gain the one times that showing “awake”. And, we have installed the sensor in correctly place( place it on the bed above 0.8~1.2 meters and remain position over an half hours).
