The Rd-03D is a small 24GHz FMCW radar module that detects people and tracks several targets at once, reporting their positions and paths over a UART link. It uses Silicon Motion's S5KM312CL SoC with an onboard PCB antenna, runs on 5V at about 200 mA, and measures 15 × 44 mm. It suits makers and product developers building presence sensing into smart home hubs, security panels and IoT devices. Compared with passive infrared sensors, it senses through plastic and glass and keeps tracking people who stand still, but it needs a microcontroller to read the serial data and is not a finished alarm product.

The Rd-03D is a compact 24GHz mmWave radar module for motion tracking and people detection. It uses a 24GHz FMCW transceiver and an S5KM312CL MCU-based SoC from Silicon Motion. It provides real-time multi-target trajectory positioning.
An onboard PCB antenna keeps installation compact. The module runs from a 5V supply at 200 mA and connects over a UART interface at 256000 bps. It can be used in smart home hubs, security panels and IoT devices, and it can be connected to microcontrollers.
