Product introduction
The Rd-01 module supports Wi-Fi & BLE, and the radar part is equipped with Silicon Power's S3KM111L chip, which is an integrated monolithic single-wave sensor SoC based on FMCW radar technology, and operates in the 24GHzk band, with a modulation bandwidth of up to 1GHz per frequency. FMCW FMCW continuous wave is utilised to detect targets in a set space. Combined with radar signal processing, accurate body sensing algorithms, it achieves high sensitivity sensing of the presence state of the human body and recognises the human body in motion and at rest.
The Wi-Fi & BLE part is equipped with BL602 chip as the core processor, which supports Wi-Fi802.11b/g/n protocol and BLE 5.0 protocol. BL602 chip has built-in low-power 32-bit RISCCPU, 276KB RAM, and rich peripheral interfaces, including SPI, UART, 12C, PWM, ADC, and GPIO, etc. The Wi-Fi & BLE part is equipped with BL602 chip as the core processor, which supports Wi-Fi802.11b/g/n protocol and BLE 5.0 protocol.
The Rd-01 module senses whether there is a moving or micro-moving human body in the area, and transmits the detection results in real-time via Wi-Fi & BL E. The module can be configured to detect the presence of a human body in the area and to detect the presence of a moving or micro-moving human body. It provides visual configuration tools, which can easily configure the sensing distance range, the sensing sensitivity of different zones, and the unoccupied delay time. Meanwhile, it supports Wi-Fi&BLE to configure the radar parameters wirelessly, which greatly improves the construction and operation and maintenance efficiency, convenient and fast.
rate, convenient and quick.

Cautions
For the mounting position on the motherboard, the following are recommended.
1. Try to ensure that the radar antenna is facing the area to be detected, and that the antenna is surrounded by an open and unobstructed area.
2. Ensure that the radar is mounted in a firm and stable position, and that any shaking of the radar itself will affect the detection effect.
3. To ensure that the back of the radar will not have object movement or vibration. Due to the radar wave has penetrating, antenna signal back flap may detect the movement of the back of the radar object. Can use metal shielding cover or metal back plate, the radar back flap shielding, attenuate the radar back object caused by the impact.
4. The theoretical distance accuracy of the radar is based on the physical resolution of 0.75 metres. On the results obtained through special algorithm processing. Due to different target size, state, RCS, etc., the target distance accuracy will fluctuate; at the same time, the distance will also fluctuate slightly.
5.In order to meet the performance of the on-board antenna, it is forbidden to place metal parts around the antenna and keep away from high frequency devices.
