JESSINIE HLK-LD2410 24g Smart Human Presence Sensor Radar Module with 1.25 to 2.54mm Dupont Cable 24GHz LD2410 Millimeter Wave Motion Switch Sensor Module with Pins

Description

The LD2410 is the 1 highly sensitive 24GHz human presence sensing module. Its working principle is to use FMCW frequency modulation continuous wave to detect the human target in the set space, combined with radar signal processing and accurate human body sensing algorithm, to achieve high sensitivity human body presence state sensing, can identify the human body in motion and static state, and can calculate the distance of the target and other auxiliary information.
This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area and output the detection results in real time. The farthest sensing distance is up to 5 meters, and the distance resolution is 0.75m. It provides a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity and unmanned delay time in different intervals to adapt to different specific application requirements.
Support GPIO and UART output, can be flexibly applied to different intelligent scenarios and end products.

The LD2410 module directly outputs the detected target state (high level for some and low level for no one) through an IO pin. At the same time, it can also output the detection result data according to the specified protocol through the serial port. The serial port output data contains the target state and distance auxiliary information, etc. The user can flexibly use it according to the specific application scenario.
The power supply voltage of the module is 5V, and the power supply capacity of the input power supply is required to be greater than 200mA.
The module IO output level is 3.3V. The default baud rate of the serial port is 256000, with 1 stop bit and no parity bit.
