01

Battery driven, ultra-low power consumption

Rd-03L is equipped with AloT millimeter wave sensor SoC ICL1112, high-performance 24GHz transmit-receive antenna and peripheral circuits.

Rd-03L can use a battery-driven ultra-low-power radar module with an average current of 0.1mA during continuous operation (1Hz reporting frequency). The low-power human presence sensing algorithm firmware is mainly used in indoor scenes to sense areas in low-power mode. Whether there is movement or slight movement of the human body inside, the detection results will be refreshed in real time.

02

Accurately identify human body micro-movements, movements and static states

Rd-03L is equipped with AloT millimeter wave sensor SoC ICL1112, high-performance 24GHz one-pitch antenna and peripheral circuits; the low-power intelligent human body sensing algorithm uses millimeter-wave sensor distance measurement technology and the ICL1112 chip's advanced proprietary radar signal processing and low-power consumption control technology to achieve precise perception of movement, micro-motion and stationary human body.

03

Plug and play, real-time reporting of detection results

Ai-Thinker Rd-03L radar module size is 20*20mm, which saves the space occupied by the product and can be quickly embedded into the product motherboard.

Rd-03L supports GPIO and UART interfaces, plug-and-play, and can be flexibly applied to different smart scenarios and terminal products.

04

Large detection angle, coverage range reaches ±60°

The Rd-03L radar needs to be wall-mounted, and the installation height is 1.5~2m. The orientation of the radar installation is shown in the figure. Among them, the X-axis direction is 0°, the Z-axis direction is 90°, and the Y-axis is perpendicular to the X-Z plane (also called the normal direction).

The wall-mounted installation height is 1.5m. At this time, the maximum motion sensing range of Rd-03L in the default configuration is 8 m in the normal direction and a conical space with an angle of ±60° in the horizontal and pitch directions.

Comprehensive application scenarios

1）Smart home

Sense the micro-motion/movement and stillness of the human body, and report the detection results for the main control module to intelligently control the operation of home appliances.

2）Smart security

Sensor access control, building intercom, electronic cat eye, etc.

3）Smart lighting

It can identify and sense micro-movement/movement/stationary human body and accurately detect human body position. It can be used in public places or home lighting equipment such as sensor lights, bulb lights, table lamps, mirror lights, etc.

4）Smart business

Recognize whether the human body is approaching or far away within the set distance interval; light up/turn off the screen in time, and dynamically adjust the screen brightness according to the distance between the human body and the screen to save power consumption.

5）New energy charging/parking monitoring facilities

It can trigger charging pile screens, parking space monitoring, wireless charging to prevent human body induction, etc.

The Rd-03L ultra-low-power radar module stands as a pinnacle of innovation, offering unparalleled precision and efficiency in human presence detection. Its advanced features, including ultra-low power consumption, accurate target recognition, and wide detection range, make it an indispensable component in various smart applications such as smart homes, security systems, lighting solutions, and more.
