LD2410C 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 body sensing algorithm to achieve high sensitivity of human presence status. The sensor can identify the human body in motion and at rest and can calculate auxiliary information such as the distance to the target. The product is mainly used in indoor scenes to sense whether there is movement or micro-movement of the human body in the area and output the results in real time. The longest sensing distance is up to 6 meters, and the resolution is 075m. 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. Due to different batches, the appearance, color and printed words of the product may vary, which will not affect the use. Colour:Blue Material:PCB Package Contents: 3 x Module
