Product Description: HLK-LD2450 Module

HLK-LD2450 is an advanced radar module operating in the 24 GHz band, designed for detecting and precisely tracking moving objects in real time. The device uses FMCW (Frequency Modulated Continuous Wave) radar technology and advanced signal processing algorithms. This enables accurate measurements of distance, angle, and speed of moving targets. The module is an excellent choice for microcontroller-based projects; it is compatible with Arduino, ESP8266, ESP32, and Raspberry Pi.

Key Technical Features

• Operating frequency: 24 GHz (ISM band, FCC and CE compliant)
• Target tracking: simultaneous tracking of up to three moving objects
• Detection range: up to 6 m
• Detection angle: ±60°
• Communication interface: UART
• Module dimensions: 15 mm x 44 mm
• Connectors: 1.5 mm pitch and 2 mm pin headers
• Interference resistance: insensitive to temperature, brightness, humidity, and light fluctuations

The module is equipped with an integrated, high-performance radar chip with one transmitting antenna and two receiving antennas, plus an MCU. It also offers good penetration through non-metallic enclosures, enabling discreet installation inside devices. The kit includes a Bluetooth antenna and cables with a 1.5 mm connector terminated with a female goldpin connector.

Example Applications

• Smart home systems
• Automatic and intelligent building lighting
• Advanced security and alarm systems
• Space management in offices, hotels, and warehouses
• IoT and AIoT projects requiring precise motion detection
• Integration with Arduino, ESP32, ESP8266, and Raspberry Pi platforms

Benefits of Using the Module

• High precision - accurate real-time measurement of object distance, angle, and speed
• Reliable operation - stable performance regardless of challenging environmental conditions
• Easy integration - support for the popular UART interface simplifies connection to external systems
• Compact dimensions - small size makes installation easy in confined spaces
• Configurable - dedicated manufacturer software available for visualization and radar parameter calibration

The recommended wall mounting height is 1.5 to 2 meters. Avoid installation in areas exposed to strong interference, such as near fans or air conditioners. When mounting inside an enclosure, ensure the material used does not block radar waves.
