HH-188-02 Radar Speed Sign Response Demo: Fast Detection and LED Speed Display

The HH-188-02 radar speed sign combines radar detection technology with LED display technology to provide clear and real-time speed information for traffic management applications.

To demonstrate the working performance of the product, we conducted a function demonstration by simulating a moving object entering the detection area. The video shows the response process from radar detection to LED display feedback.

Fast Radar Detection and LED Display Response

The HH-188-02 radar speed sign consists of a radar detection module, control system, and LED display.

When a moving object enters the detection range, the radar sensor quickly captures movement information and sends the signal to the control system.

After processing, the LED speed display updates the information promptly, allowing users to clearly see the response process of the device.

Intelligent Speed Display and Overspeed Warning Function

In addition to displaying speed information, the HH-188-02 provides intelligent visual warning functions.

The device supports three-digit speed display with a maximum display speed of 199 km/h.

Based on preset speed limits, the LED display provides different visual feedback:

• Normal speed condition: Displays the current speed with a green smiley face symbol.
• Overspeed condition: Displays the current speed with a red sad face symbol to remind users to reduce speed.

By combining LED speed display, color indicators, and visual symbols, the device makes speed information easier to understand.

IP67 Outdoor Protection

Designed for outdoor applications, the HH-188-02 radar speed sign features an IP67 protection rating, providing reliable protection against dust and water.

With durable construction and stable operation, it is suitable for applications such as school zones, residential roads, industrial areas, parking areas, and construction areas.

Conclusion

The HH-188-02 radar speed sign response demonstration shows how radar detection and LED display technologies work together to provide fast and clear speed feedback.

With real-time speed display, intelligent overspeed warnings, and IP67 outdoor protection, the HH-188-02 provides a practical solution for speed management and traffic safety applications.
