presence detectors sensor 24GHz Radar Sensor for Focused Detection in Small Areas like Toilets
1. Feature
MSA215 99 is a 24GHz radar sensor based on Merrytek's patented multi-array antenna. Its antenna has a high gain and a very narrow detection range. Combined with Merrytek’s unique software algorithm, it can accurately detect minor movements brought by humans in almost all indoor spaces and best presence detection solution for workspace and toilet cubicle, etc small-space scenes.

9. Detection signal
The product detects human moving, minor moving, and presence signals, and realizes the detection of human-existing/no-human in a non-sleep state. The following is a description of the moving, minor moving, and presence signals:
*Moving signal: detect the human significant moving (walking) in the detection area.
*Minor moving signal: detect the human slightly 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.
*Presence signal: detect human abdominal and thoracic expansion behaviors caused by breathing, but not detect moving signal and minor moving signal.
