Description
The Hi-Link HLK-LD2451 is an advanced 24GHz FMCW radar sensor module specifically developed for vehicle status monitoring and traffic detection applications. Using Frequency Modulated Continuous Wave (FMCW) radar technology, the module can accurately detect vehicle presence, distance, speed, and orientation within its sensing range.
Designed for reliable outdoor and semi-outdoor environments, the HLK-LD2451 enables real-time traffic data acquisition and supports intelligent transportation systems. Its high detection range and wide coverage angle allow it to monitor multiple lanes, high-speed roads, and non-motorized lanes with precision.
With flexible communication interfaces, including UART and GPIO, and built-in Bluetooth connectivity for configuration and live monitoring, the HLK-LD2451 is easy to integrate into modern smart traffic and vehicle detection solutions.
