LD2410B 24GHz Radar Human Presence Sensing Module with BT+Radar Test Board 5V LD2420 Millimeter Wave

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.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.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 & terminal productsDue to different batches, the appearance, color and printed words of the product , which will not affect the useMaterial: PCBcolour: BluePackage Contents: 1 x Module1 x Radar Test Board (the Test Board has serial port chip CH340)1 x USB cableOnly 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.
