Description :
Ai-Thinker Rd-03D V2 24G Multi-Target Human Movement Trajectory Positioning and Tracking Radar Module is an advanced 24GHz FMCW millimeter-wave radar sensor designed for accurate human presence detection, multi-target tracking, motion trajectory recognition, speed measurement, and distance sensing. Developed by Ai-Thinker, this intelligent radar module is powered by the high-performance S5KM312CL millimeter-wave radar SoC, delivering reliable real-time detection with low power consumption and excellent resistance to environmental interference. Whether you are developing smart home devices, industrial automation systems, security solutions, IoT products, or robotics applications, the Rd-03D V2 offers a powerful and dependable sensing solution.
The module operates in the 24GHz K-Band with a maximum sweep bandwidth of 0.25GHz, utilizing advanced FMCW (Frequency Modulated Continuous Wave) radar technology. Unlike conventional PIR motion sensors, the Rd-03D V2 can detect moving, micro-moving, and stationary human bodies with high precision. This allows it to accurately identify human presence even when a person is sitting, standing, or sleeping without significant movement, making it ideal for intelligent occupancy detection systems.
Powered by the integrated S5KM312CL radar transceiver and microcontroller SoC, the module combines advanced radar signal processing with built-in intelligent positioning and tracking algorithms. It can simultaneously detect multiple targets within the monitoring area and continuously report their position, movement trajectory, distance, and speed in real time. These intelligent features significantly reduce development complexity, enabling engineers and developers to quickly integrate accurate radar sensing into their products.
The Ai-Thinker Rd-03D V2 is specifically designed to recognize different human motion states, including walking, running, micro-movement, and complete rest. This capability makes it an excellent choice for smart lighting systems, automatic doors, occupancy monitoring, energy-saving building automation, elderly care systems, smart offices, and intelligent public facilities. By accurately distinguishing human movement patterns, the module helps improve automation efficiency while minimizing false detections.
One of the key advantages of the Rd-03D V2 is its outstanding anti-interference capability. Unlike infrared sensors, its performance is not affected by lighting conditions, temperature changes, smoke, dust, or common wireless communication signals such as Wi-Fi and Bluetooth. This ensures stable and reliable operation in homes, offices, hospitals, shopping malls, schools, factories, warehouses, hotels, and other indoor environments where consistent detection performance is essential.
The built-in intelligent radar processing algorithm enables high-speed target recognition and tracking while maintaining low power consumption. This makes the module suitable for battery-powered devices as well as always-on smart automation systems. Developers can quickly configure the module through its communication interface, reducing product development time and simplifying system integration.
Thanks to its compact size, professional-grade performance, and intelligent sensing capabilities, the Ai-Thinker Rd-03D V2 is widely used in smart home automation, IoT devices, industrial automation, robotics, security systems, occupancy detection, people counting, human presence sensing, intelligent lighting, automatic equipment control, access control systems, smart healthcare devices, public infrastructure, research projects, and embedded electronic applications.
Whether you are a student, maker, electronics hobbyist, embedded system developer, robotics engineer, or product manufacturer, the Ai-Thinker Rd-03D V2 24G Multi-Target Human Movement Trajectory Positioning and Tracking Radar Module provides an advanced, reliable, and cost-effective solution for next-generation intelligent sensing applications. Its accurate multi-target tracking, real-time human presence detection, motion trajectory analysis, speed measurement, ranging capability, low power consumption, and excellent environmental adaptability make it one of the best 24GHz FMCW radar modules available for modern automation and smart electronic projects.
