1. Product Introduction
▫️ Overview
Rd-03L_V2
- Rd-03L_V2 is an ultra-low-power millimeter-wave human presence sensor developed by Ai-Thinker Co., Ltd. It integrates simplified 24 GHz radar sensor hardware and low-power human presence detection intelligent algorithm firmware, powered by the AloT millimeter-wave sensor SoC ICL1112, high-performance 24GHz 1T1R antenna, and peripheral circuits.
- The low-power intelligent human detection algorithm combines millimeter-wave distance measurement technology with the ICL1112's advanced proprietary radar signal processing and low-power control capabilities to achieve precise detection of moving, 微动 (subtle movements), and stationary humans. Optimized for indoor scenarios, the firmware continuously monitors for human presence in low-power mode and updates detection results in real time.
▫️ Features
- Smart Home: Detects human presence and distance to intelligently control home appliances.
- Smart Security: Enables motion-activated access control, alarms, and camera linkage applications.
- Smart Lighting: Provides precise human detection for public or home lighting (e.g., motion-sensing bulbs, table lamps).
- Smart Commerce: Detects human proximity within configurable ranges, activates displays on approach, and maintains device operation during presence.
- New Energy Charging/Parking Monitoring: Triggers EV charging station displays, monitors parking spaces, and prevents unauthorized access to wireless charging areas.
