Hi-Link HLK-LD2410C-P 24GHz Human Presence Radar Sensor

Product Description

The Hi-Link HLK-LD2410C-P is a high-precision 24GHz human presence detection radar sensor designed for smart home and intelligent sensing applications. Using FMCW millimeter-wave radar technology, it detects moving and stationary human targets within a defined range and provides real-time presence data.

With support for GPIO and UART output, the HLK-LD2410C-P can be easily integrated into microcontrollers, automation systems, lighting controllers, security devices and smart IoT products. It features configurable detection zones, adjustable sensitivity and unmanned delay timing, making it adaptable for both residential and commercial environments.

The sensor provides a maximum detection distance of up to 5–6 meters with a wide ±60-degree detection angle, allowing reliable and stable sensing performance even in complex indoor environments. A visual configuration tool is also provided for easy setup, calibration and range tuning.
