Special Features

  • In addition to sensitive to the movement of the human body, the static, micro-motion, sitting and lying human body that cannot be identified by the traditional scheme can also be sensitively sensed
  • It has good environmental adaptability, and the induction effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuation
  • Good shell penetration, can be hidden in the shell inside the work, no need to open holes on the surface of the product, improve the product appearance
  • The maximum sensing distance is up to 5 meters, Flexible configuration of the farthest sensing distance and the sensitivity of each distance on the door, to achieve flexible and fine personalized configuration
  • With Bluetooth function, you can directly use APP to debug radar parameters without receiving serial ports

Description

LD2410B is a highly sensitive 24GHz human presence state sensing module. Its working principle is to use FMCW frequency modulated continuous wave to detect human targets in the set space, combined with radar signal processing and precise human body sensing algorithms, to achieve high sensitivity human presence state sensing, which can recognize human bodies in both moving and stationary states, and calculate auxiliary information such as the distance of the target.
This product is mainly used in indoor scenes, sensing whether there is movement or micro movement of the human body in the area, and outputting real-time detection results. The farthest sensing distance can reach 5 meters, with a distance resolution of 0.75m. Provide visual configuration tools that can easily configure sensing distance range, sensing sensitivity in different intervals, and unmanned delay time to meet different specific application requirements.
Supports GPIO and UART outputs, plug and play, and can be flexibly applied to different intelligent scenarios and terminal products.
