Ai-Thinker Rd-03L Low Power 24GHz Radar Sensor

The Ai-Thinker Rd-03L is the ultimate solution for energy-efficient motion sensing. Unlike standard radar modules that require constant mains power, the Rd-03L is an Ultra-Low Power module designed specifically for battery-operated and solar-powered applications.

Industry-Leading Energy Efficiency

Powered by the ICL1112 millimeter-wave SoC, this module achieves an incredibly low power consumption of just 55μA, with an average working current of less than 100uA (at 1Hz reporting). This makes it possible to run smart detection systems on coin cell or AA batteries for extended periods.

No Compromise on Performance

Despite its low power usage, the Rd-03L delivers powerful performance. It uses 24GHz FMCW technology to detect moving, micro-moving, and static human bodies up to 8 meters away. It also features a “No Blind Zone” design, effectively sensing targets as close as 0.2 meters.

Key Features

• Battery Optimized: Ultra-low power consumption (μA-Class) suitable for wireless, battery-powered setups.

• Advanced Chipset: Equipped with the ICL1112 sensor chip for high-sensitivity detection.

• Long Range: Detects human presence up to 8 meters with a wide ±60° angle.

• Zero Blind Spots: Proximity induction starts at just 0.2m.

• Smart Config: Visual tools allow you to configure distance intervals, trigger thresholds, and unattended delay times.

• Easy Integration: Standard 20x20mm size with 2.54mm DIP pins and UART/GPIO support.

Technical Specifications

Typical Application Scenarios

• Smart Doorbells: Battery-operated video doorbells that wake up only when someone approaches.

• Solar Security: Outdoor motion sensors powered by small solar panels.

• Portable Electronics: Wearables or portable gadgets requiring presence detection.

• Remote Monitoring: Sensing in locations where running power cables is difficult.
