Hailingke 60G high-precision millimeter-wave radar LD6004 multi-target 3D human presence sensing serial communication--EngrWorld

HLK-LD6004 is a radar sensing module developed by Hailingke based on the ADT6101P chip. It monolithically integrates a 57~64GHz RF transceiver system, 2T2R AIP packaged antennas, 1MB flash, a radar signal processing unit, and an ARM® Cortex®-M3 core. This module is based on the FMCW signal processing mechanism and combined with radar signal processing algorithms to achieve high-sensitivity human body state sensing. It can identify moving, slightly moving, and stationary human bodies, and can calculate auxiliary information such as target distance and speed.

This module is based on a two-transmit and two-receive antenna configuration, with a wide beam angle, suitable for ceiling mounting. It supports GPIO and UART signal output, and can be flexibly applied to different intelligent scenarios and products.

2. Product Features

 Radar detection based on FMCW (Frequency Modulated Continuous Wave) signals

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

 Supports side-mounted mode switching, with a maximum sensing distance of 6m

 Maximum support for 3-person target movement tracking, with output of personnel position coordinates (x, y, z)

 Can realize detection of moving and stationary indoor personnel, accurate identification within the interval, supports division of sensing intervals, and shields interference inside and outside the interval

 Universal UART interface, providing communication protocols

 Supports UART parameter adjustment to meet different scenario requirements

 Compact size, only 25*31.5mm, supporting two connection methods: pin header plug-in and patch mounting

 Not affected by environment factors such as temperature, humidity, noise, air flow, dust, and light

3. Application Scenarios

 Smart home appliance applications

Based on the detection of the presence or absence of people in the room, adjust the working mode of home appliances in real time (working, standby, shutdown) to realize the intelligence of home appliances.

 Human body sensor light applications

Sense whether there is a human body in the current space, automatically control the light switch, such as public scene lighting, office lighting, and various types of sensor lights.

 Smart home scenario applications

For places such as homes, hotels, offices, and bathrooms, real-time detection of the presence or absence of people entering or existing in the place is required, so as to realize security, electrical control, personnel monitoring, etc. It can be combined with relevant IoT support platforms to achieve effective applications in relevant places.
