HLK-LD2454 24G Multi-Target Human Motion Trajectory Radar Sensor Module Single-Transmitter, Dual-Receiver via Serial Communication (Module Test Kit)

JMT HLK-LD2454 24G Multi-Target Human Motion Trajectory Radar Sensor Module Single-Transmitter, Dual-Receiver via Serial Communication Product Description LD2454 is a 24GHz radar module that enables real-time tracking of moving target positions within the detection area, and outputs distance, angle, and velocity information of moving targets via serial communication. It is mainly used in typical indoor environments such as homes, offices, and hotels for positioning and tracking of moving human bodies. The LD2454 module outputs detection result data directly via the serial port according to the specified protocol. The serial port output data includes information such as the position and speed of up to three targets, which users can utilize flexibly based on their specific application scenarios.

The module operates at a supply voltage of 5V, and the input power supply must be capable of delivering more than 200mA. The modules I/O output level is 3.3V, and the default serial port baud rate is 256, 000, with 1 stop bit and no parity bit.
