Description

The HLK-LD102 module utilizes a fixed-frequency Doppler radar principle to detect motion and micro-movements within a defined spatial cone. It integrates a directional antenna (1TIR), intermediate frequency demodulation, signal amplification, and digital processing on a single compact board. This integrated design provides high stability and consistency while suppressing clutter and harmonic interference.

Engineered for reliability in varied environments, the sensor is unaffected by non-metallic obstructions and common ambient conditions, making it suitable for concealed installations. Its serial communication port allows for fine-tuning of operational parameters like sensing range and trigger delay, enabling customized integration into automated control systems for lighting, security, or advertising displays.

Key Features

  • X-band (10.525GHz) Doppler radar sensing core for reliable motion detection.
  • Integrated signal conditioning with intermediate frequency demodulation and digital processing.
  • Configurable sensing range (0.1-2m) and trigger delay via serial communication interface.
  • Compact, low-profile design suitable for wall-mounted or embedded installation.
  • High immunity to environmental interference from temperature, humidity, and particulates.
  • Low power consumption design for battery-powered or energy-sensitive applications.
  • Does not penetrate walls, ensuring localized detection and privacy.

Applications

  • Automatic lighting control for corridors, stairwells, and storage rooms.
  • Proximity activation for interactive advertising displays and kiosks.
  • Energy-saving systems for smart cabinets, vending machines, and appliances.
  • Presence detection in security and occupancy monitoring systems.
  • Non-contact triggering for automated doors or sanitization equipment.

Frequently Asked Questions

What is the operating voltage range for the HLK-LD102 radar sensor?

The HLK-LD102 operates from 3.3V to 12V DC, providing flexibility for integration with both 3.3V logic microcontrollers (like ESP32) and standard 5V or 12V industrial control systems. Its low current draw of 6-12mA makes it suitable for battery-powered applications.

How do I adjust the detection range and trigger delay?

The module features a serial communication port that allows parameter configuration. You can connect to this port using a USB-to-TTL adapter and send specific commands to set the sensing distance (between 0.1 and 2 meters) and the output trigger hold time after detection.

Can this radar sensor detect motion through walls or glass?

No. The 10.525GHz X-band signal used by the HLK-LD102 does not effectively penetrate solid walls, ensuring detection is localized to the intended area. This prevents false triggers from adjacent rooms and is a key feature for privacy-conscious installations.

What is the beam width or detection angle of this sensor?

The sensor has a conical detection pattern with an angle of approximately 110° (±10°). This wide field of view makes it ideal for covering areas like room corners or above doorways without requiring precise alignment during installation.
