HLK-LD012-5G is an ultra-low power 5.8G radar sensor launched by Hilink Electronics, with an overall power consumption of about 68uA. The module size is 20mm*20mm. The module fully integrates 5.8GHz microwave circuit, intermediate frequency amplifier circuit and signal processor. It has high integration and good production consistency. The peripheral is equipped with a small planar antenna to ensure the performance of the sensor while greatly reducing total measurement. The sensor can be used to detect the presence of human body or various scenes of moving target sensing, including smart home, Internet of Things, and smart lighting. It is especially suitable for low-power battery-powered scenes such as night lights, solar street lights, and wireless cameras.

Features:

  1. Low Power: Consumes only 68 µA.
  2. Frequency: Operates at 5.8 GHz.
  3. Adjustable Distance: 16 options via P2 pin.

Package Includes:

1 x Hi-Link HLK-LD012, 5.8GHz 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.
