Rd-03D is a radar module equipped with Silicon Microelectronics' S5KM312CL chip. S5KM312CL is an integrated microcontroller millimeter wave sensor SoC based on FMCW radar ceiver technology. It operates in the 24 GHz K-band with a maximum sweep bandwidth of 0.25GHz. This module uses FMCW waveform and S5 series chip's proprietary advanced signal processing technology, combined with MCU's proprietary radar signal processing and built-in intelligent positioning and algorithm, to detect multiple targets in a designated area and report the results in real time. Users can quickly Develop corresponding targeting products. The Rd-03D module accurately senses the motion status of the human body and the area. It is equipped with an intelligent algorithm to realize motion trajectory recognition and , and can measure the speed and distance of targets in the area. The recognition speed is faster and the power consumption is lower. The module can be quickly configured and is suitable for publicity facilities.<br><br>It can intelligently distinguish the human body in motion, micro-motion and stillness, and control the switch of the equipment. This module has good resistance to external interference and is not affected by wireless signals such as WIFI.
