1. Product introduction

  LD2410C is a highly sensitive 24GHz human presence sensing module developed by Hailingco Electronics. Its working principle is to use FMCW FM continuous wave to detect the human target in the set space, combined with radar signal processing, accurate human sensing algorithm, to achieve high It can identify the human body in motion and at rest, and calculate the distance of the target and other auxiliary information.

  This product is mainly applied in indoor scenes, sensing whether there is a moving or slightly moving human body in the area, and outputting the detection results in real time. The farthest sensing Distance up to 5 meters, distance resolution 0.75m. provide visual configuration tools, can easily configure the sensing distance range, different zones of sensing The visual configuration tool can easily configure the sensing distance range, sensing sensitivity and unmanned delay time in different zones to suit different specific application requirements.

  Support GPIO and UART output, plug-and-play, can be flexibly applied to different intelligent scenarios and end products

3. Application scenarios

1. In addition to sensitive sensing of moving human body, for the traditional solution can not identify the static, micro-movement, sitting and lying human body can also be sensitive sensing.

2. Good environmental adaptability, the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations.

3. good shell penetration, can be hidden inside the shell work, no need to open holes in the product surface, improve the product aesthetics.

4. flexible configuration of the farthest sensing distance and the sensitivity on each distance door, to achieve flexible and fine personalized configuration.

5. With Bluetooth function, you can use the APP to debug the radar parameters directly without catching the serial port
