LD2450A is a 24G radar sensor module that can realize waving and human proximity sensing. It consists of a millimeter wave radar chip, a one-transmitter and two-receiver microstrip antenna, an MCU and peripheral auxiliary circuits. Adopting FMCW working mode, target detection technology and ranging and angle measurement algorithms, it can realize left waving and right waving gesture recognition, human proximity sensing and ranging functions under limited bandwidth conditions. It can be used in indoor intelligent control scenarios such as homes, offices, and hotels.
