Product introduction

HLK-LD6003B is a radar sensing module developed based on ADT6101P chip, which integrates a 57-64GHz RF transceiver system on a single chip, 2T2R PCB microstrip antenna, 1MB flash, radar signal processing unit, ARM ® Cortex ®- M3 kernel. This module is based on the FMCW signal processing mechanism, combined with radar signal processing algorithms, to achieve high-sensitivity human state sensing. It can recognize motion and micro movements, stationary human bodies, and calculate auxiliary information such as target distance and speed.

This module is based on the form of two transmitting and two receiving antennas, with a wide beam angle, suitable for ceiling installation. Supports GPIO and UART signal output, which can be flexibly applied to different intelligent scenarios and products.

Product Features

• Radar detection based on FMCW frequency modulated continuous wave signal

• Large detection angle, supporting horizontal ± 60 ° and pitch ± 60 ° detection

• Supports top side installation mode switching, with a maximum sensing distance of 6m

• Supports up to 3 people for target motion tracking, with output of x, y, and z coordinates for personnel positions.

• Capable of detecting the movement and stillness of indoor personnel, accurately identifying within intervals, supporting the division of sensing intervals, and shielding interference inside and outside the intervals

• Universal UART interface, providing communication protocol

• Support UART parameter adjustment to meet different scene requirements

• Compact size, only 25 * 31.5mm, supports both pin insertion and patch connection methods

• Not affected by temperature, humidity, noise, airflow, dust, light and other environmental factors
