The LD2410 is a high-sensitivity 24GHz human presence sensing module. Its working principle utilizes FMCW (Frequency Modulated Continuous Wave) to detect human targets within a designated space. Combined with radar signal processing and a precise human presence sensing algorithm, it achieves high-sensitivity human presence sensing, capable of identifying both moving and stationary human bodies. It can also calculate auxiliary information such as the target's distance. This product is primarily used in indoor scenarios to detect the presence of moving or slightly moving human bodies within an area, outputting detection results in real time. The maximum sensing distance is up to 5 meters, with a distance resolution of 0.75 meters. It provides a visual configuration tool, allowing easy configuration of the sensing distance range, sensing sensitivity in different ranges, and inactive latency, adapting to various specific application needs. Supporting GPIO and UART outputs, it is plug-and-play and can be flexibly applied to different smart scenarios and terminal products. Operating Frequency Band: 2.4GHz ~ 24.25GHz Power Supply Requirements: DC 5V, power supply capacity >200mA Average
