A:
PCB boards need to be customized, and radar modules need high stability.

A:
1) The thickness of the board (or the laminated structure of the board) and the dielectric constant of the board.

2) The consistency of sheet thickness and dielectric constant is most closely related to the consistency of the module.

A:
1) The influence of the buzzer switch on the radar module:

→ The buzzer switch will disturb the power supply. The buzzer and switch should be placed far away from the radar when designing the structure;

→The buzzer switch and 10.525G signal will be mixed. The product software will shield the interference during design, and ignore the radar induction signal when the buzzer switch and indicator light flash;

→The indicator light and 10.525G signal will be mixed, the sensor software alg

A:
1) Stagger as much as possible in space, and extend the distance between the antenna of the IoT module and the antenna of the radar;

2) Stagger the time as much as possible, and shield the radar sensor signal when the IoT module communicates;

3) Stagger the frequency as much as possible, and avoid the corresponding communication frequency by adjusting the frequency of the radar sensor.

A:
1) The sensing distance is tested under ideal conditions. The actual sensing distance is related to the hanging height, the openness of the test site, the height and shape of the tester, and the pace of the tester. The sensing distance of the final product is recommended to be subject to the actual measurement;

2) When the radar sensors are densely distributed, try to ensure that the antennas of the radar are parallel to each other to avoid direct illumination between the antenna surfaces
