The Hi-Link HLK-LD2411, 24GHz Ranging Radar Sensor is a human distance sensing and gesture recognition module. it can recognize the user's gesture lifting and releasing movements, as well as detecting the user's movement into and away from the toilet, and outputting GPIO signals through the detected movements to allow the manufacturer's micro-controller to control the opening or closing of the toilet lid. The Hi-Link HLK-LD2411, 24GHz Ranging Radar Sensor module uses a 5V supply and the radar beam is designed in a wide and narrow way, with a horizontal angle (4 patch) of approximately ±20° and a vertical angle of ±40°, with adjustments made to the antenna placement direction depending on the scenario. For toilet applications, a narrow horizontal beam is recommended to avoid false triggering of the human body passing by.


Features:

  1. Plug and play, easy assembly method
  2. Sensing distance up to 2 meters, gesture recognition distance up to 1 meter
  3. Detection angle coverage up to ±30 degrees
  4. Distance sensing distance can be adjusted via Bluetooth
  5. The ultimate value for money choice

Package Includes:

1 x Hi-Link HLK-LD2411, 24GHz Ranging 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.
