7. Detection signal
The product detects human movement, minor movement, and presence signals, and realizes the detection of human-existing/no-human in the sleep state. The following is a description of the moving, minor moving, and presence signals:
l Moving signal: detect the human significant moving (walking) in the detection area.
l Minor moving signal: detect the human slight moving in the detection area, such as leaning forward, leaning forward and back, swinging limbs, shaking head, typing, playing with mobile phones, and so on.
l Presence signal: detect human abdominal and thoracic expansion behaviors caused by breathing, but not detect moving signal and minor moving signal.
