Ai-Thinker Rd-03D-
Rd-03D is a radar module developed by Ai-Thinker, equipped with the S5KM312CL chip. S5KM312CL is an integrated microcontroller millimetre wave sensor SoC based on FMCW radar transceiver technology. It 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 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 module has. good resistance to external interference and is not affected by wireless signals such as WIFI.

Precautions for radar installation
- In the motherboard installation position, it is recommended that the following several ways:
- As far as possible ensure that the radar antenna is opposite to the test area and that the antenna around open without sunscreen.
- Ensure that the radar installation position is firm, and stable, shaking will influence the effect of the detection of the radar itself.
- Make sure there is no movement or vibration on the back of the radar. Due to the penetrating nature of radar waves, the back lobe of the antenna signal may detect moving objects on the back of the radar. A metal shield or metal backplane can be used to shield the radar back lobe to reduce the impact of objects on the back of the radar.
- The range accuracy of the target will fluctuate due to the different sizes, states, RCS, etc., And the farthest distances fluctuate slightly.
- If there are multiple radars in the 24GHz band, do not beam correctly and install them as far away as possible to avoid possible mutual interference.
- To meet the performance of the onboard antenna, do not place metal parts around the antenna, far away from high-frequency devices.
- The power input voltage range is 5V, and the power ripple is required to be controlled within 100. Users need to consider the corresponding ESD and lightning surge EMC design.
