Hi-Link HLK-LD105, 10GHz Motion Detection Radar Sensor designed based on X-band radar chip, with a center frequency of 10.525GHz. The design adopts fixed frequency, directional transmitting and receiving antenna (1T1R), integrates intermediate frequency demodulation, signal amplification and digital processing functions, and opens the communication serial port. It has the ability to set delay, adjustable sensing range and light intensity detection, which is convenient for customers to adjust parameters independently. It has the advantages of not penetrating walls, anti-interference, small size, It has the advantages of good suppression of clutter and high-order harmonics, high stability and consistency, etc. This product is suitable for embedded concealed design, is not affected by temperature/humidity, oil smoke, water mist, etc., and can be widely used in smart lighting, security, home, etc

Features:

  1. Operating frequency 10.525GHz
  2. Based on the principle of Doppler rad
  3. This product is positioned for micro/motion sensing scene applications

Package Includes:

1 x Hi-Link HLK-LD105, 10GHz Motion Detection Radar Sensor

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
