24GHz radar presence sensor（ON/OFF version）
MSA246S 99 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 to automatically turn on or turn off lighting etc electrical appliance.

Product dimension
Initialization
When powered on,sensor indicator will turn off after flashing for 10S and will enter a 10S detection cycle,if there’s presence detected,then sensor will report presence and enter hold time calculating,if absence detected,then sensor will report absence.During initialization,sensor will not detect moving signal and you can use our MH10/MH18 remote or rotation switch to adjust detection area、hold time and daylight sensor etc parameter.
