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.
The LD2410B human body sensing module adopts 24GHz millimeter wave radar sensor technology, which has obvious advantages in human body sensing applications compared to other solutions:
1. In addition to being sensitive to the movement of the human body, it can also be sensitive to static, micro moving, and sitting and lying human bodies that cannot be recognized by traditional methods;
2. Has good environmental adaptability, and the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity, and light fluctuations;
3. It has good shell penetration and can be hidden inside the shell to work, without the need for holes on the surface of the product, improving the product's aesthetics;
4. Flexible configuration of the farthest sensing distance and sensitivity on each distance door, achieving flexible and refined personalized configuration; 5. Equipped with Bluetooth function, it can directly use the APP to debug radar parameters without connecting to a serial port
