HLK-LD101

1. Summary

HLK-LD101 is an X-band radar module working at 10.525GHz. Based on the Doppler effect, this design uses fixed-frequency, directional transmitting and receiving antennas, which are first combined with chip integration technology and microwave antennas on the market.

It has the characteristics of anti-interference, small size, no wall penetration, high stability, good consistency, and good clutter and high-order harmonic suppression effect.

The on-board integrated IF demodulation, signal amplification, digital processing, light intensity detection, timing and other functions are integrated on the module, and the serial port function is opened at the same time, which is convenient for users to adjust relevant parameters.

This product adopts pulse power supply mode, and the average power consumption can be reduced to 7mA.
