Rd-01 radar module, which supports Wi-Fi&BLE. The radar part is equipped with S3KM111L chip of Sidian Micro, working in 24GHz k band, each frequency up to 1GHz modulation bandwidth. The working principle is to use FMCw FM continuous wave to detect human body targets in the set space combined with radar signal processing and accurate human body induction algorithm to realize highly sensitive human presence state induction, identify human body in motion and static state, and calculate auxiliary information such as the distance of the target.

The Wi-Fi&BLE part uses the BL602 chip as the core processor and supports wi-Fi 802.11b/g/n and BLE5.0 protocols. This product is mainly used in indoor scenes, sensing whether there is a moving or twitching human body in the area, real-time transmission of detection results through Wi-Fi&BLE, providing visual configuration tools, which can easily configure the range of induction distance, induction sensitivity of different sections and unmanned delay time. It supports GPIO and UART output and wi-Fi&BLE wireless configuration of radar parameters, which can be flexibly applied to different intelligent scenarios and terminal products.

Installation precautions:

The following methods are recommended for the installation position on the mainboard:

1. Try to ensure that the radar antenna is facing the area to be detected, and the antenna is open around without occlusion. 2. To ensure that the radar installation position is firm and stable, the shaking of the radar itself will affect the detection effect.

3, to ensure that there will be no movement or vibration on the back of the radar. Since radar waves are penetrating, antenna signals

The back flap may detect moving objects on the back of the radar. A metal shield or metal backplane can be used to shield the radar back flap to weaken the influence of objects on the back of the radar.

4. The theoretical range accuracy of radar is obtained by special algorithm based on the physical resolution of 0.75m

The result of Because of the different size, state and RCS of the target, the accuracy of the target range will fluctuate. And the farthest distances fluctuate a little bit.

5. In order to meet the performance of the onboard antenna, it is forbidden to place metal parts around the antenna and keep away from high-frequency devices.

This product needs to be installed in a suitable environment. If it is used in the following environments, the detection effect will be affected:

6. There are non-human objects in continuous motion in the induction area, such as animals, curtains that continue to swing and are facing the air outlet

Large green plants, etc.

7. There is a large area of strong reflectors in the induction area, which will cause interference to the radar antenna.
