Product Description:

The Hi-Link LD2420 is a high-sensitivity 24GHz radar sensor module designed for precise human presence detection. Utilizing FMCW (Frequency Modulated Continuous Wave) radar technology, it detects human targets in both motion and stationary states with exceptional accuracy. This module outperforms traditional PIR sensors, offering enhanced sensitivity and the ability to calculate approximate target distances. With a maximum sensing range of 8 meters (wall-mounted) or 5 meters (ceiling-mounted), the LD2420 is perfect for indoor applications requiring real-time presence detection.


Features:

  1. Advanced Sensing Technology:

    • Based on FMCW radar for accurate detection of moving and stationary human bodies.
  2. High Sensitivity and Accuracy:

    • Detects up to 8 meters (wall-mounted) and 5 meters (ceiling-mounted) with a distance accuracy of ±0.35 meters.
  3. Real-Time Data:

    • Outputs real-time sensing results with a data refresh rate of 10Hz.
  4. Compact Design:

    • Small form factor (~20mm x 20mm) for easy integration into various applications.
  5. Wide Sensing Angle:

    • ±60 degrees sensing angle ensures broad coverage.
  6. Low Power Consumption:

    • Operates at 3.3VDC with a current draw of ~50mA, making it energy-efficient.
  7. Communication and Output Options:

    • UART communication protocol with a default baud rate of 256000.
    • Digital output pin for direct HIGH/LOW human detection signal.
  8. Durable Build:

    • Operates reliably in extreme temperatures ranging from -40°C to +85°C.

Specifications:

  • Manufacturer: Hi-Link
  • Model: LD2420
  • Frequency Band: 24 – 24.25GHz (FCC and CE compliant)
  • Modulation: FMCW (Frequency Modulated Continuous Wave)

  3. OT2: Digital output pin (HIGH = Human detected, LOW = No detection)
  4. GND: Ground
  5. 3V3: Supply voltage (3.0 – 3.6VDC)

How to Use:

  1. Power Supply:

    • Connect the 3V3 pin to a 3.0 – 3.6VDC power source and the GND pin to ground.
  2. Communication Setup:

    • Use the UART interface (TX and RX pins) to communicate with a microcontroller or computer.
    • Configure the communication protocol using the default baud rate of 256000.
  3. Digital Output Monitoring:

    • Monitor the OT2 pin for HIGH/LOW signals to detect human presence without UART communication.
  4. Installation:

    • For wall-mounted applications, set the sensor at an appropriate angle for maximum detection range (up to 8 meters).
    • For ceiling-mounted setups, install the sensor at a height of up to 5 meters.
  5. Integration and Testing:

    • Integrate the sensor into your system and use the provided tools and resources to calibrate and monitor performance.

Applications:

  1. Smart Home Automation:
