Main Highlights:
- High-Performance Antenna: The module features a high-performance 24GHz one-pitch microstrip antenna with a narrow beam, providing high resolution and strong anti-interference capabilities.
- Precise Detection: It can detect human targets in both micro-motion and motion states, with a maximum sensing distance of 6 meters for moving bodies and 3.5 meters for slightly moving bodies.
- Accurate Ranging: The module supports high-precision distance measurement, with a range of 30cm to 600cm, maintaining an accuracy of ±5cm within 350cm and ±5% beyond 350cm.
- Low Power Consumption: The average current during continuous operation is 48mA at a report frequency of 20Hz.
- Compact Size: With an ultra-small module size of 28x24mm, it is designed for easy integration and plug-and-play functionality.
- Visualization Tools: The module comes with tools to configure detection range intervals and set sensitivity according to distance gates.
Application Scenarios:
- Smart Home: Used for intelligent control of home appliances by sensing micro-movements and distances of the human body.
- Smart Security: Applications include sensor access control, building intercoms, and electronic peepholes.
- Smart Lighting: Enhances lighting systems in public and home settings by accurately detecting human presence and movements.
- Smart Business: Optimizes power consumption by dynamically adjusting screen brightness based on the distance between the human body and the screen.
- New Energy: Facilitates applications like charging pile screens and parking space monitoring.
Rd-03D Radar Module
The Rd-03D radar module features ICLEGEND MICRO’s S5KM312CL chip and is designed to provide accurate sensing of human body movement status, trajectory identification, and tracking. Like the Rd-03E, it operates at a frequency of 24GHz with FMCW waveform technology.
Main Highlights:
- High-Performance Antenna: It includes a high-performance 24GHz one-transmit and two-receive microstrip antenna with a narrow beam, offering high resolution and strong anti-interference.
- Multi-Target Detection: The module can detect multiple targets in a designated area, providing real-time reporting of distance, angle, speed, and position.
- Extended Detection Range: Capable of detecting targets up to 8 meters away.
- Intelligent Tracking: Utilizes built-in algorithms for multi-person movement trajectory identification and tracking.
- Compact Size: With dimensions of 15x44mm, it is designed for easy integration.
- Visualization Tools: Supports visual configuration for multi-target detection and real-time display of tracked targets.
Application Scenarios:
- Smart Home: Controls home appliances based on the sensed movement and distance of the human body.
- Smart Bathroom: Precise control of devices like automatic toilet seat opening and closing.
- Smart Lighting: Enhances lighting systems by accurately detecting human presence and movements.
- Smart Business: Optimizes screen brightness and power consumption based on human proximity.
