60GHz 3D Detection model SC1240AR3

SC1240AR3 is an extremely low-power and intelligent CMOS 60GHz radar sensor device and available for 3D (including 1D, 2D) sensing without an external MCU.
It contains a high-performance signal processing unit and detects the 3D position of moving objects and the presence of the objects in any specific area.
