Introduction

AI Translation

The HLK-LD2402 is a stationary human presence sensor integrating 24GHz sensor hardware with an intelligent human micro-motion detection algorithm firmware. Its hardware comprises an AIoT millimeter-wave sensor, a high-performance 24GHz single-transmit single-receive antenna, and peripheral circuitry. The algorithm employs millimeter-wave ranging technology combined with advanced signal processing techniques to achieve precise detection of motion, micro-motion, and human presence. This sensor is primarily designed for indoor scenarios, enabling real-time detection of human activity within a monitored area with continuously refreshed results. It supports a maximum detection range of 10 meters for moving subjects, with configurable range settings, trigger and hold thresholds for different zones, and unoccupied reporting time. GPIO and UART interfaces are provided for plug-and-play operation across a wide range of smart applications. Automatic detection threshold generation is also supported to minimize manual tuning, improve accuracy, and simplify installation.
