【Product Feature】

MSA211 B is a 24GHz radar sensor based on Merrytek patented orthogonal half-wave bending antenna. Its antenna has high gain and wide detection range and is combined with Merrytek’s unique software algorithm. It can accurately detect minor movements brought by human in almost all indoor spaces and provide fast and accurate front-end sensing input for presence detectors, smart hotel, smart office and other scenes.

1. Exclusive Merrytek Lifebeing Presence Detection

2. Accurate Presence/Absence Output

3. Daylight Sensor Available

4. Casambi APP Control Available

5. 24Ghz ISM Band Millimeter Wave Radar

6. Presence, minor motion and motion detection range are highly coincide

7. Round radiation. Effectively managing a whole space by a single sensor

8. Absence switch to Presence within 0.5S

【Product Initialization】

Our sensor indicator will turns off after flashing for 20 seconds once it’s powered on.And sensor does not detect moving signal during initialization. You can turning ON/OFF indicator, hold time and detection area can be controlled by Casambi APP.

【Factory Setting】

Detection Area:100% Hold Time:1min Indicator light:open

【Detection Radiation】

MSA211 B is highly suggested flush mounting and its detection radiation is as below:

【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.
