Ai-Thinker Rd 03E 24G Millimeter Wave Radar

Ai-Thinker Rd-03E is a 24GHz millimeter wave radar module designed for human distance measurement, gesture recognition, and presence sensing in interactive IoT systems. Built around the S3KM111L chip, this Ai-Thinker radar sensor combines FMCW waveforms, radar signal processing, and onboard algorithms to report real-time distance and gesture data for embedded development.

This Ai-Thinker 24GHz radar module is especially useful for gesture control, smart interaction panels, contactless sensing, and human detection projects. With the official host computer tool, developers can view radar output in real time and adjust parameters for better gesture sensing, distance detection, and radar-based UI applications.

Features

  • 24GHz FMCW radar for presence sensing, real-time distance measurement, and gesture recognition.
  • S3KM111L chip solution with strong real-time performance and radar algorithm support.
  • Up to 1GHz modulation bandwidth for accurate target detection in designated areas.
  • Supports human body movement, micro-movement, and gesture-related sensing tasks.
  • UART communication with a default baud rate of 256000bps for host integration.
  • Well suited for Ai-Thinker radar interaction, touchless control, AIoT sensing, and smart terminals.

FAQ

What makes Rd-03E different from a basic radar presence sensor?
Ai-Thinker Rd-03E adds human distance measurement and gesture recognition, so it is better for interactive sensing and touchless control systems.

Can Rd-03E be used in AIoT projects?
Yes. This Ai-Thinker radar module is designed for AIoT, interactive terminals, and embedded products that need distance and gesture data over UART.

Is the module suitable for contactless user interfaces?
Yes. Its 24GHz radar sensing and gesture recognition features make it a good fit for contactless interaction design.

Important Notice:

  • Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Arlington warehouses. If an item is out of stock in these locations, it will be marked as "Pre-order". You can still place an order for these items.
  • Pre-order Fulfillment: For "Pre-order" items, we arrange the most efficient logistics solution to ensure you receive your goods as quickly as possible. Your package may be shipped directly from our Shenzhen warehouse. Alternatively, as part of our standard restocking process, we may transport the goods to our Munich or Arlington warehouse first (typically taking 5-10 business days) before dispatching them to you.
  • Split Shipments: If your order contains both in-stock and Pre-order items, we will prioritize shipping the in-stock items from the local warehouse immediately. The remaining Pre-order items will be sent to you in a separate shipment once they are ready.

3. International Warehouse

Our products are stored in our Munich, Arlington, and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.
