24GHz Large-space presence sensor（Dry contact version）
MSA200D RC is a 24GHz radar sensor based on Merrytek patented orthogonal antenna. Its antenna has high gain and wide detection range. Combined with Merrytek’s unique software algorithm and FMCW modulation,it can accurately detect micro movements brought by human in almost all indoor spaces and provide fast and accurate front-end sensing input for smart home, smart hotel, smart office and other scenes.

Product dimension
Initialization
When powered on,sensor indicator will turn off after flashing for 10S and will enter a 20S detection cycle,if there’s presence detected,then sensor will enter hold time calculating,if absence detected,then sensor relay will disconnect.During initialization,sensor will not detect moving signal and you can use our MH10 remote to adjust detection area、hold time and daylight sensor etc parameter.
Factory setting
Detection Area: 4m(medium sensitivity), Hold Time: 30S, Daylight Sensor: Disable, Indicator light: open
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:
