HLK-LD2451 Motorcycle/ Tricycle Blind Spot Auxiliary Radar module
Introducing the HLK-LD2451, a sophisticated 24GHz mobile vehicle status sensing module from Hi-Link Electronics. This high-sensitivity module leverages FMCW FM continuous wave technology, paired with advanced radar signal processing and precise algorithms, to accurately detect vehicles across a designated range. It excels at identifying vehicles at varying distances—from immediate proximity to up to 100 meters away—while also calculating and outputting crucial data such as target speed, angle, and distance.
Designed specifically for outdoor applications, the HLK-LD2451 focuses on reliable vehicle detection, providing real-time output for both near and far targets. Its impressive sensing range extends up to 100 meters, making it ideal for diverse environmental conditions.
With both GPIO and UART output options, this module offers plug-and-play functionality, ensuring seamless integration into a wide array of intelligent systems and terminal products.
Features
- Effortless Setup: Enjoy simple assembly and plug-and-play functionality for quick deployment.
- Extended Sensing Capability: Detect vehicles at distances up to 100 meters, configurable to any range between 10-100m.
- Intelligent Adaptability: Features multi-level intelligent parameter settings to dynamically adjust to various operational scenarios.
- Mobile Debugging: Utilize convenient mobile tools for debugging and configuration.
- Broad Coverage: A wide detection angle capable of monitoring up to 3 traffic lanes.
- Certified Compliance: Operates on the 24GHz ISM band, with FCC and CE spectrum regulation certifiable status.
- Cost-Effective Solution: Delivers superior performance as the ultimate cost-effective choice for vehicle detection.
Application
The HLK-LD2451 vehicle sensing module’s ability to detect and identify vehicles across diverse distances, combined with its multi-level parametric settings, makes it highly applicable across a variety of intelligent and terminal products. It is particularly effective in the following situations:
- Highway Intersections: When strategically installed at highway junctions, this module precisely senses vehicle trajectories, assesses proximity, and gathers vital data such as speed and distance for enhanced traffic management.
- Non-motorized Roads: Effectively detects blind spots in the rear visual field, significantly reducing the risk of accidents caused by rear-approaching vehicles or sudden lane changes.
- Motorways: Provides critical detection of vehicles at considerable distances behind the driver, aiding in the accurate determination of following vehicle trajectories and improving driver awareness.
