Ai-Thinker Rd-03L

Rd-03L is a battery-powered ultra-low power radar module developed by Shenzhen Ai-Thinker
Technology Co., Ltd. The module includes extremely simplified 24GHz millimeter wave
sensor hardware and low-power Human Presence sensing intelligent algorithm firmware. Rd-03L is equipped with AIoT millimeter wave sensor SoC ICL1112, high-performance
24GHz-receiver antenna and peripheral circuit. ICL1112 is an industry-leading μA-Class
24g single-transmit single-receiver millimeter wave sensor chip, which has ultra-low power
consumption (55 μA) and ultra-high remote exploration capability. It works in the K-band
of 24 GHz, and uses FMCW frequency modulation continuous wave to detect targets in the set
space. Rd-03L adopts millimeter wave sensor distance measurement technology and ICL1112
chip advanced proprietary radar signal processing and low power consumption control
technology to realize accurate perception of motion, micro motion and standing human body. Low-Power Human body presence induction algorithm firmware is mainly used in indoor
scenes. It detects whether there is moving or micro-moving human body in the area in a
low-power mode, and refreshes the detection

The maximum sensing distance of the Rd-03L to the moving human body is 8 meters. It is easy
to configure the sensing distance range, trigger and maintenance thresholds in different
intervals, the status of the human body, the frequency of reporting the distance from the target
human body, and the time when no one reports. Rd-03L supports GPIO and UART interfaces, plug and play, and can be flexibly applied to different intelligent scenarios and terminal
products.
