1. Introduction
The Hi-Link HLK-LD6001A is a 60G human tracking occupancy radar sensor module designed for advanced human presence detection and tracking. Unlike traditional sensing methods such as vision, infrared, and laser, this millimeter-wave radar operates effectively regardless of lighting conditions, providing unobtrusive and continuous room monitoring. It is engineered with internal personnel perception monitoring and privacy protection features, making it suitable for modern home and smart building applications.
This module utilizes domestically produced chips, ensuring autonomous and controllable operation. It can accurately track and locate multiple individuals indoors, detecting both movement and static states (e.g., reading, sleeping). The HLK-LD6001A also features advanced interference suppression capabilities, effectively ignoring disturbances from elements like curtains or green plants. Its design emphasizes low cost, high reliability, and high performance.
2. Product Overview and Features
The HLK-LD6001A module is a multi-target human sensing radar operating at 60GHz. It offers robust capabilities for tracking and detecting human presence in various environments.
- Multi-Target Tracking: Capable of tracking up to 10 individuals simultaneously, providing their movement trajectories and real-time positions.
- Static Presence Detection: Detects human presence even when individuals are stationary, such as when reading or sleeping.
- Interference Suppression: Strong ability to suppress false targets and environmental interference from objects like curtains, green plants, and multipath reflections.
- High Sensitivity: Exhibits high sensitivity in detecting micro-moving targets, including subtle movements like shaking or waving.
- Communication: Utilizes TTL serial port communication for data output.
- Installation: Designed for ceiling installation, enabling unobtrusive track detection.

4. Setup and Installation
4.1 General Installation
The HLK-LD6001A module is designed for "on top install," typically referring to ceiling mounting. This placement allows for optimal overhead detection and tracking of human movement within a room, providing an unobtrusive sensing solution.
4.2 Wiring and Connections
The module communicates via a TTL serial port. Refer to the pinout diagram (Figure 3) for proper connections. A typical setup, especially for testing or development, involves connecting the module to a serial port board like the CH340, as shown in the test kit (Figure 4).
- 3V3: Power supply input (3.3V).
- GND: Ground connection.
- TX: Transmit data (connect to RX of your serial receiver).
- RX: Receive data (connect to TX of your serial transmitter).
- NRST: Reset pin.
- TMS, TCK: Test/debug pins (typically not used for standard operation).
Ensure all connections are secure and correctly aligned to prevent damage to the module or connected devices. Always verify power supply voltage before connecting to avoid overvoltage.
5. Operating Instructions
Once the HLK-LD6001A module is correctly powered and connected via its TTL serial port, it begins sensing its environment. The module outputs data related to human presence, movement trajectories, and real-time positions through the serial interface.
- Power On: Apply 3.3V to the 3V3 pin and connect GND. The module will initialize.
- Data Output: The module will transmit detection data via the TX pin. This data can be received and processed by a microcontroller or computer connected to the RX pin of the module.
- Interpreting Data: The serial data will contain information about detected individuals, their movement paths, and current locations. Specific data protocols and formats would typically be detailed in a separate software development kit (SDK) or communication protocol document provided by the manufacturer.
- Detection Range: The module is optimized for indoor human tracking and occupancy detection. Ensure the installation height and orientation are suitable for the desired coverage area.
For detailed information on the serial communication protocol and data interpretation, please refer to the official technical documentation or contact Hi-Link technical support.
6. Maintenance
The HLK-LD6001A radar module is designed for reliable, long-term operation with minimal maintenance. To ensure optimal performance:
- Keep Clean: Ensure the module's surface, especially the radar antenna area, is free from dust, dirt, or obstructions. Use a soft, dry cloth for cleaning if necessary.
- Environmental Conditions: Operate the module within its specified environmental conditions (temperature, humidity) to prevent damage.
- Power Supply: Use a stable and clean 3.3V power supply. Fluctuations or incorrect voltage can affect performance or damage the module.
- Physical Inspection: Periodically inspect the module and its connections for any signs of physical damage or loose wiring.
7. Troubleshooting
If you encounter issues with your HLK-LD6001A module, consider the following troubleshooting steps:
- No Power/Indicator:
- Check power supply connections (3V3 and GND) and ensure the voltage is stable at 3.3V.
- Verify the power source is functioning correctly.
- No Data Output:
- Confirm TX/RX connections are correctly wired (TX of module to RX of receiver, RX of module to TX of transmitter).
- Check serial port settings (baud rate, parity, data bits, stop bits) on your receiving device. These are typically specified in the module's communication protocol document.
- Ensure there are actual human movements or presence within the detection zone.
- Inaccurate Detection:
- Verify the module is installed in an optimal position, ideally on the ceiling, with a clear line of sight to the detection area.
- Check for any new obstructions or sources of interference in the environment.
- Ensure the module's surface is clean.
- Module Overheating:
- Ensure adequate ventilation around the module.
- Verify the input voltage is not exceeding 3.3V.
If problems persist, consult the official technical documentation or contact Hi-Link technical support.
