HLK-LD2410B is a high-sensitivity 24GHz human presence status sensing module developed by Hi-Link Electronics. It utilizes FMCW frequency-modulated continuous wave technology to detect human targets within a defined space. The module employs radar signal processing and a human body induction algorithm, enabling precise detection of both moving and stationary human bodies. Additionally, it calculates auxiliary data such as target distance.
This module is primarily designed for indoor applications, providing real-time detection of human presence within a range of up to 5 meters with a distance resolution of 0.75m. It features a visual configuration tool that allows easy customization of sensing distance, sensitivity, and delay time to suit various application requirements. With support for GPIO and UART output, it offers plug-and-play functionality, making it adaptable for different smart scenarios and terminal products.
