HLK-LD1020 10.525Ghz Radar Motion Detection Sensor Module

HLK-LD1020 10.525Ghz Radar Motion Detection Sensor Module

HLK-LD1020 is a micro/motion detection module designed based on the X-band radar chip with a center frequency of 10.525 GHz. The module design adopts fixed-frequency, directional transmitting and receiving antenna (1T1R), combines intermediate frequency demodulation, signal amplification and digital processing functions, and is capable of delay adjustment, adjustable detection range and light intensity detection.

This The product has the advantages of not penetrating walls, anti-interference, small size, good suppression of clutter and higher harmonics, high stability and consistency. The integrated algorithm inside the chip can directly broadcast detection results without the need for an external single-chip microcomputer.

The module's power consumption in pulsed power supply mode is at the microampere level. This module is mainly aimed at low-cost, low-power applications.

This product is suitable for buried concealed installation and is not affected by temperature/humidity, oil mist, water mist, etc. Bulb lights, down lights, ceiling lights etc. It can be widely used in various lamps such as.
