Hi-link 24G vehicle motobycle bitrycle ranging and speed measurement millimeter wave radar LD2451 vehicle status monitoring sensor module

Product profile

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, 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, 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

 HLK-LD2451 vehicle sensing module can detect and recognize vehicles close to or far away from the vehicle, supports multi-level parameterization, and can be widely used in various intelligent products and terminal products, commonly used types are as follows 

• Highway intersection Installed at highway intersections, it senses the direction of vehicles traveling on the highway as close or far away, speed, distance, etc. 

• Non-motorized road

Detecting the blind spot in the rear field of vision, avoiding a car accident caused by a vehicle approaching from behind and changing lanes suddenly 

• Motorway Detecting distant vehicles behind, assisting the driver to determine the trajectory of the vehicle behind them 

• Smart Scene Sensing the approach of vehicles, automatic control of road gates, garage doors and other scenes automatically opened or closed
