Small Detection range 24GHz Presence Radar sensor with DC to DC dry contact output
1. Feature
MSA215D 99 is a 24GHz radar sensor based on Merrytek's patented multi-array antenna. Thanks to its high gain, concentrated detection range, and Merrytek’s unique software algorithm, it can accurately detect human presence information within a small range with clear boundaries like workplace and toilet cubicles. Thus it can provide fast and accurate human presence/absence information for smart office work stations ,small meeting cubicles and smart toilet solutions.

7. Detection signal
The product detects human moving, minor moving, and presence signals, and realizes the detection of human-existing/no-human in 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 slight moving in the detection area, such as leaning forward, leaning forwarder 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.
