Special Features

  • LD2410B is a high sensitivity 24GHz human presence state sensing module developed by Hailingke Electronics
  • The module uses FMCW FM continuous wave to realize high sensitivity human presence state sensing, can identify the human body in motion and static state, and can calculate the distance of the target
  • It has good environmental adaptability, and the sensing effect is not affected by the ambient environment such as temperature, brightness, humidity and light fluctuation
  • This product is mainly used in indoor scenes to detect whether there is a moving or twitching human body in the area, and output the detection results in real time. The longest induction distance is up to 5 meters, and the range resolution is 0.75m.
  • It supports GPIO and UART output, plug and play, and can be flexibly applied to different intelligent scenarios and terminal products
