About This LD2410B is a highly sensitive 24GHz human presence state sensing module Its working principle is to use FMCW FM continuous wave to detect the human body target in the set space, combine with radar signal processing and accurate human body sensing algorithm to achieve high sensitivity human body presence state sensing, recognize the human body in motion and static state, and calculate the distance of the target and other auxiliary information This product is mainly used in indoor scenes, sensing whether there is a moving or inching human body in the area, and outputting the detection results in real time. The maximum sensing distance can reach 5 meters, and the distance resolution is 0.75 m Provide visual configuration tools, which can easily configure the sensing distance range, sensing sensitivity and unmanned delay time in different sections to meet different specific application requirements It supports GPIO and UART output, plug and play, and can be flexibly applied to different intelligent scenarios and terminal products Overview Brand : EC Buying Color : Blue Power Source : DC Power Supply Item Weight : 0.01 Kilograms Maximum Range : 5 Meters, 6 Meters
