HLK-LD2451 is a high-sensitivity 24GHz mobile vehicle status sensing module developed by Hi-Link Electronics. Its working principle is to use FMCW FM continuous wave to detect the target within the detection range, combined with radar signal processing, and accurate algorithm recognition, to realize high-sensitivity vehicle status detection, which can identify the vehicles close or far away, and calculate the output of the target's speed, angle, distance, and other auxiliary information.
This product is mainly used in outdoor scenes, sensing whether there is a vehicle close to or far away from the area, real-time output detection results, and the longest sensing distance up to 100m. The longest sensing distance can be up to 100 m. Mobile software is provided to easily configure parameters such as sensing distance, speed, target direction and sensitivity to meet different application requirements. Support GPIO and UART output, plug and play, can be flexibly applied to different intelligent scenes and terminal products.

Application scenarios
The HLK-LD2451 vehicle sensing module can detect and recognize vehicles at various distances, supporting multi-level parameterization, and is widely applicable in a range of smart and terminal products. It is commonly used in the following scenarios:
- Highway Intersection: Installed at highway intersections, the module senses the direction of vehicles traveling on the highway, determining whether they are close or far, along with speed, distance, and other data.
- Non-motorized Road: The module detects blind spots in the rear field of vision, helping to prevent accidents caused by vehicles approaching from behind and sudden lane changes.
-
Motorway: It detects distant vehicles behind the driver, assisting in determining the trajectory of the vehicle following them.
