Product profile
HLK-LD020 is a motion sensing module designed based on an X-band radar chip, with a center frequency of 5.8GHz. This module design adopts fixed frequency, directional transmission, and reception technology Line (1T1R), integrating functions such as intermediate frequency demodulation, signal amplification, and digital processing, with the ability to set delay, adjust sensing range, and detect light intensity.
This product has the characteristics of not penetrating walls and being resistant to advantages include interference, small size, good suppression of clutter and high-order harmonics, high stability, and consistency. Module initialization time is short, and it also has a fast inspection mode, which can be installed in lighting fixtures for testingEasy to operate, can effectively accelerate production testing. This module is mainly aimed at low-cost application fields.
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 types of lamps, such as fluorescent lamps, bulb lamps, tube lamps, ceiling lamps, etc

The delay time is the time it takes to maintain this state after triggering, with a default value of 5 seconds;
The blocking time refers to the time it takes for the output state to flip and trigger a non response again, with a default value of 2 seconds;
Power on initialization: After 4 seconds of high output from the module's O port, turn off the light and start normal detection mode after 3 seconds;
Different testing environments or exercise objectives, the test results can be there can be differences;
The metal casing has a shielding effect on radar electromagnetic waves, affects perceived distance;
The above test results were tested on a standard testing site, please consult the relevant department for specific testing environment and conditions related technical personnel.
