Ai-Thinker Rd-03L V2 is a 24GHz human presence sensor optimized for ultra-low-power radar detection in battery-powered and always-on devices. This Ai-Thinker radar module combines a compact footprint, FMCW millimeter wave sensing, and low standby power to support presence detection, occupancy sensing, and smart building automation where efficiency matters.
Built around the ICL1112 radar solution, Ai-Thinker Rd-03L V2 supports human presence detection for moving, slightly moving, and stationary targets. Its low-power profile makes this 24GHz mmWave sensor a strong option for battery devices, smart lighting, security sensing, and occupancy-aware IoT systems that need longer runtime and reliable indoor detection.
