Ai-Thinker Rd-03_V2 24GHz mmWave Human Presence Radar Sensor

Upgrade your automation projects with the Ai-Thinker Rd-03_V2, a high-performance 24GHz millimeter-wave radar module. Built around the powerful S1KM0000 chip from ICLEGEND MICRO, this module offers superior sensitivity and a wider modulation bandwidth of up to 1GHz per single-frequency scan.

Next-Generation Sensing Technology

Using advanced FMCW (Frequency-Modulated Continuous Wave) technology, the Rd-03_V2 detects targets with incredible precision. Unlike standard PIR sensors, it can identify three distinct states of human presence:

1. Stationary: Detects a person sitting still or reading.

2. Moving: Tracks walking or running subjects.

3. Subtle Motion: Recognizes micro-movements like typing or breathing.

Visual Configuration Tools

One of the standout features of the Rd-03_V2 is its ease of use. It supports visual configuration tools, allowing you to easily set sensing distance ranges, adjust sensitivity for specific zones, and configure delay times for when no human is present—all without complex coding.

Key Features

• Advanced Chipset: Equipped with the S1KM0000 SoC for robust processing and lower power consumption.

• High Bandwidth: Operates in the 24GHz K-band with a modulation bandwidth of up to 1GHz, providing higher resolution data than standard modules.

• Real-Time Detection: Instantly reports human presence to control switches, lights, or alarms.

• Smart Tuning: Visual tools make it easy to define detection zones and shield outside interference.

• Versatile Integration: Ideal for smart home, security, and energy management systems.

Technical Specifications

Typical Application Scenarios

• Smart Lighting: Precision control for table lamps and bulbs; lights stay on even if you are reading quietly.

• Smart Security: Motion-activated access control and camera linkage for accurate intrusion detection.

• Smart Commerce: Activates display screens when a customer approaches a specific distance range.

• Energy Management: Monitors EV charging stations and parking spaces to prevent unauthorized access.

• Home Automation: Intelligent control of appliances based on real-time room occupancy.
