Features:
Obvious Advantages in Human Body Sensor Applications:
1. In addition to being sensitive to the movement of the human body, it can also be sensitive to static, micro moving, and sitting and lying human bodies that cannot be recognized by traditional methods;
2. Has good environmental adaptability, and the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity, and light fluctuations;
3. It has good shell penetration and can be hidden inside the shell to work, without the need for holes on the surface of the product, improving the product's aesthetics;
4. Flexible configuration of the farthest sensing distance and sensitivity on each distance door, achieving flexible and refined personalized configuration; 5. Equipped with Bluetooth function, it can directly use the APP to debug radar parameters without connecting to serial port
