Description

The HLK-LD2410-P utilizes Frequency-Modulated Continuous Wave (FMCW) radar technology operating in the 24GHz ISM band. This principle allows it to distinguish between moving and stationary human targets by analyzing the frequency shift of the reflected signal, enabling precise presence sensing even for subtle micro-movements like breathing. The module integrates advanced radar signal processing and proprietary human body sensing algorithms to filter out environmental noise and non-human targets.

Designed for indoor environments, it features a wide 5-12V DC input range for compatibility with various power supplies and control systems. Its compact form factor (7mm x 35mm) and support for multiple mounting methods (ceiling, wall) make it suitable for integration into finished products and IoT devices. The module is designed to meet FCC and CE spectral regulations for commercial deployment.

Frequently Asked Questions

What is the operating voltage range for the HLK-LD2410-P module?

The module operates on a wide DC voltage range of 5 to 12 volts. This flexibility allows it to be powered directly from common microcontroller power rails (5V) or higher voltage adapters (12V) without requiring an additional voltage regulator, simplifying integration into various electronic systems.

How do I configure the detection zones and sensitivity?

Configuration is performed using a dedicated visual PC tool provided by Hi-Link, connected via the module's UART interface. This software allows you to set the maximum detection distance (up to 5m), adjust sensitivity levels within up to three distinct distance zones, and define the delay time before an 'unoccupied' state is reported after the target leaves the area.

Can this sensor detect a person who is completely still?

Yes, the HLK-LD2410-P uses advanced 24GHz FMCW radar technology and signal processing algorithms capable of sensing micro-movements, such as breathing and slight posture shifts. This allows it to reliably detect the presence of a stationary human body, distinguishing it from inanimate objects.

What is the difference between the GPIO and UART output modes?

The GPIO output provides a simple high/low digital signal indicating a general occupied/unoccupied status, ideal for basic triggering. The UART (Serial) output provides detailed data packets containing information like target distance, motion energy level, and specific zone detection, enabling more complex logic and data logging in your host controller.
