Cảm biến hiện diện và quét tay X-band 10GHz Human Presence Sensing & Hand Sweep HLK-LD102 Hi-Link dùng kỹ thuật phát sóng radar ở tần số 10GHz cùng các thuật toán để phát hiện người trong cự ly gần, cảm biến cũng nhận diện các thao tác như vẩy tay tay ở phía trước. Cảm biến có mức giá rẻ, phù hợp với các ứng dụng bật tắt thiết bị bằng cử chỉ tay hoặc phát hiện người ở cự ly gần.
LD102 is an X-band radar module operating at 10.525GHz. It uses a fixed-frequency, directional transmitting and receiving antenna (1TIR), integrates intermediate frequency demodulation, signal amplification and digital processing functions, and opens a communication serial port. It has the ability to set delays and adjustable sensing range, which is convenient for customers to adjust parameters independently.
It has the characteristics of anti-interference, small size, no wall penetration, high stability, good consistency, good clutter and high-order harmonic suppression. It is suitable for embedded concealed design, not affected by temperature and humidity, oil smoke, water mist, etc., and can be used in non-contact sensing control fields such as local space lighting or advertising machines.
