1. Product Introduction
▫️Overview
Rd-03H
Rd-03H is a 24GHz K-band radar module developed by Ai-Thinker Co., Ltd.based on the S1KM0000 chip from SiDianWei (1GHz single-frequency scanning modulation bandwidth)
Capable of real-time detection of stationary, moving, or micro-motion human presence within monitored areas. Includes visual configuration tools for easy setup of detection range, sensitivity zones, and idle timeout settings.
▫️Key Applications
- Smart Home Automation: Detect human presence and distance to intelligently control appliances
- Security Systems: Access control triggers, alarm activation, camera integration
- Intelligent Lighting: Precise presence detection for automatic lighting control (bulbs, lamps, mirror lights)
- Commercial Solutions: Zone-based proximity detection, screen activation, persistent device operation during presence
- EV Charging/Parking Systems: Charger screen activation, parking occupancy detection, wireless charging safety
