Rd-03D is a radar module developed by Ai-Thinker, which is equipped with the S5KM312CL chip. S5KM312CL is an integrated microcontroller millimeter wave sensor SoC based on FMCW radar transceiver technology.

Rd-03D works in 24 GHz K-band with a maximum sweep bandwidth of 0.25 GHz. The module adopts the advanced signal processing technology of FMCW waveform and S5 series chip, combined with MCU's radar signal processing and built-in intelligent positioning and tracking algorithm, which can detect multiple targets in the specified area and report the results in real-time, and users can quickly develop the corresponding target positioning and tracking products.

The Rd-03D module accurately senses the human body and regional motion state, carries an intelligent algorithm to realize motion trajectory recognition and tracking, and realizes speed measurement and ranging of targets in the region, with faster recognition speed and lower power consumption. The Rd-03D module can be configured quickly and is suitable for all kinds of public publicity facilities.

It can intelligently distinguish the human body in the form of movement, micro-movement, and rest, and control the switch of equipment. The Rd-03D module has good resistance to external interference and is not affected by wireless signals such as WIFI.
