Ai-Thinker Rd-01 is a 24GHz millimeter wave radar module that combines radar detection with Wi-Fi and BLE connectivity. Based on the official Ai-Thinker documentation, this Ai-Thinker radar module uses the S3KM111L radar chipset together with a BL602 wireless processor to detect human presence, motion, and subtle movement while sending results through wireless links in real time.

Rd-01 is designed for smart home sensing, smart security, smart lighting, occupancy detection, parking and charging monitoring, and other connected sensing products. Official materials highlight flexible distance and sensitivity configuration, zone-based tuning, no-human delay configuration, and wireless parameter setup, which makes this Ai-Thinker 24GHz radar module practical for both deployment and maintenance.

Features

• 24GHz FMCW radar sensing with Wi-Fi + BLE connectivity on one module.
• Detects human presence, motion, and subtle movement with high sensitivity.
• Wireless parameter configuration for easier installation and maintenance.
• Distance, sensitivity, and no-human delay can be configured for different scenarios.
• Supports multiple installation styles including surface mount, plug-in, and cable connection.
• Suitable for Ai-Thinker occupancy sensing, smart lighting, smart retail, and smart security products.

Specifications

Applications

• Smart home occupancy sensing and connected automation.
• Smart lighting control for lamps, bulbs, and area-based activation.
• Smart security systems with human presence detection and motion linkage.
• Parking, charging, and commercial monitoring where distance-aware radar sensing is needed.

Other Content

Rd-01 is a strong option when you want both sensing and wireless communication in a single Ai-Thinker module. Compared with a basic radar-only part, this design makes it easier to connect detection data to cloud, gateway, or local control systems.
