This is a motion sensing module designed based on an X-band radar chip, with a center frequency of 10.525GHz. The design adopts fixed frequency, directional transmitting and receiving antennas (1T1R), integrating functions such as intermediate frequency demodulation, signal amplification, and digital processing. It has the ability to set delay, adjust sensing range, and detect light intensity This product has the advantages of not penetrating walls, anti-interference, small size, good suppression of clutter and high-order harmonics, high stability and consistency. The module initialization time is short, and it also has a fast inspection mode. It is easy to install and test in lighting fixtures, which can effectively accelerate production testing. Due to different batches, there may be differences in product appearance and printed text, which not affect use Colour: Random Color, don't accept the specified color Material:PCB Package Contents: 1 x Radar sensor module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
