Introduction Product
HLK-LD1020 is a micro/motion sensing module designed based on X-band radar chip with a center frequency of 10.525GHz.
The module design adopts fixed-frequency, directional
transmitting and receiving antenna (1T1R), integrates the functions of intermediate frequency demodulation, signal amplification and digital processing, and has the ability of delay setting, adjustable sensing range and light intensity detection.
This 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 output the detection results without the need for an external single-chip microcomputer.
In the module pulse power supply mode, the power consumption is at the microampere level.
This module is mainly aimed at low-cost, low-power applications.
This product is suitable for embedded concealed installation, and is not affected by temperature/humidity, oil fume, water mist, etc. It can be widely used in various lamps, such as bulb lamps, down lights, ceiling lamps, etc.; Doorbell, peephole, door lock, low-power camera,
etc.
