Ai-Thinker Rd-01 24G Radar Human Body Induction Module/Radar +WiFi+BLE Module Sensor Rd-01 with Antenna – User-freindly and Convenient

Ai-Thinker Rd-01-

Rd-01 is a radar module, which supports Wi-Fi&BLE. The radar part is equipped with an S3KM111L chip. The S3KM111L is an integrated monolithic single-wavelength sensor SoC based on FMCW radar technology. Operates in the 24 GHz k-band with up to 1 GHz modulation bandwidth per frequency. Use FMCW frequency modulation continuous wave to detect the target in the set space.

Combined with radar signal processing and a precise human body sensing algorithm, it realizes high-sensitivity human body presence status sensing and recognizes the human body in motion and static state. The Wi-Fi&BLE part is equipped with a BL602 chip as the core processor, which supports Wi-Fi 802.11b/g/n protocol and BLE5.0 protocol. The BL602 chip has a built-in low-power 32-bit RISC CPU, 276KB RAM and rich peripheral interfaces, including SPI, UART, I2C, PWM, ADC GPIO, etc.

The operating principle of the Rd-01 human body sensing module is to use FMCW frequency-modulated continuous wave to detect the human body target in the set space, and to realize high-sensitivity human body presence state sensing by combining radar signal processing and accurate human body sensing algorithm, which can identify the human body in motion and static state, and calculate the auxiliary information such as the distance of the target.

This product is mainly used in indoor scenes, sensing whether there is a moving or micro-moving human body in the area, and outputting the detection results in real-time. The farthest sensing distance can reach 5 meters, and the distance resolution is 0.75m. Provide a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity in different intervals, unmanned delay time, etc., to meet different specific application requirements. It supports GPIO and UART output and can be flexibly applied to different intelligent scenarios and terminal products.

Applications

Human Sensor Light Control-

Rd-01 radar module has the characteristics of high sensitivity and high reliability, and can quickly switch on and off candescent lamps, fluorescent lamps, induction lamps, mirror lamps, etc. in public places or home lighting by sensing the distance of the human body.

Take the mirror light for girls’ skincare and make-up as an example. When the mirror light senses the presence of a human body, it will automatically light up. When there is only a slight movement of the arm or a static movement for a long time, the mirror light will still remain on, and will not turn off the light due to the static sitting state. After the person leaves, the light will turn off.

Human body induction wake-up of equipment such as advertising screens-

Rd-01 radar is suitable for all kinds of home appliance screens, commercial advertising screens, and access control panels to trigger and activate applications. In terms of installation, the Rd-01 radar is small in size and has a hidden design, which can penetrate the screen panel or the non-metallic casing of the electrical appliance without opening the panel. When a person appears in front of the screen, the advertising screen senses the human body to play the advertisement, and it will not stop playing because the person is still watching. When no one passes by, the advertising screen enters the off-screen state, which greatly improves the light pollution caused by the advertising screen, and also achieves environmental protection and power saving.

Smart Security-

Human body presence sensing radar technology can be used to realize human body sensing alarms. When someone enters the monitored area, the device can automatically trigger an alarm, and realize App push and other linkage alarms through WiFi/BLE.

Rd-01 radar is an important technical equipment in the field of security, which can quickly detect and accurately intrude targets, and timely alarm and alert. The Rd-01 radar has powerful performance and small size and has obvious advantages compared with other infrared sensor alarms. In terms of indoor security, the human body presence sensor radar recognizes personnel intrusion and can cooperate with the camera to trigger the linkage application. If there is an abnormal situation, the linkage WiFi/BLE will transmit the data to the app of the owner’s mobile phone, and send out an alarm prompt to improve residential safety.

Smart Appliances-

The Rd-01 radar can detect the presence and static state of the human body. Therefore, when a person appears in front of the screen, the radar will trigger the lighting when it senses the human body, and immediately link with other smart home appliances. off, saving time and electricity.

The Rd-01 radar module can also be intelligentized for various space management scenarios such as offices and hotels. Put the human presence sensing product with Rd-01 in the conference room to manage the occupancy situation, control the lighting or power supply by human touch, and automatically cut off the power when there is no one, so as to achieve the purpose of energy-saving. In building a smart hotel, Rd-01 can realize intelligent management of guest rooms. When the guest enters the room, the system can automatically turn on the lights, play music, etc., to improve the guest’s experience; when the guest leaves the room, the system can automatically turn off the lights, air conditioning and other equipment to save energy.
