24G millimeter wave vehicle speed measurement radar sensor module HLK-LD2415H remote speed measurement serial communication

Product introduction

The HLK-LD2415H velocity radar is a millimeter wave radar module that integrates microstrip antennas, RF circuits, and signal processing circuits, directly outputting target velocity information. Can be used for long-distance car speed measurement up to 180 meters or more, using integrated RF chips, with extremely high frequency stability and a speed measurement accuracy of 1KM/h. Widely used for speed warning and warning of road bends and intersections on various types of roads such as highways, urban and rural trunk roads, city and county level highways, and urban and rural trunk roads.
