<p>LD2410B is a high-sensitivity 24GHz human presence sensing module. The working principle is to use FMCW frequency modulated continuous wave to detect human targets in a set space, combined with radar signal processing and precise human sensing algorithm, to achieve high-sensitivity human presence state sensing, which can identify human bodies in motion and stationary states and calculate Auxiliary information such as the distance to the target.</p> <p>The product is mainly used in indoor scenes to sense whether there is movement or mini-movement of the human body in the area and output the results in real time.</p> <p>The sensing distance is up to 6 meters, and the resolution is 0.75m. A configuration tool is provided to configure the sensing distance range, sensing sensitivity in different intervals, unattended delay time, etc. Supports GPIO and UART output, plug-and-play and can be flexibly applied to different smart scenarios and terminal products.</p> <p>Due to different batches, the appearance, color and printed words of the product , which not affect the use</p> <p>Material: PCB</p> <p>colour: Blue</p> <p>Package Contents: </p> <p>1 x Module</p> <p>Only the above package content, other products are not included.</p> <p>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.</p>
