In recent years, safety accidents have occurred frequently due to sudden heavy rainfall or continuous rainfall causing water level rise, especially in areas such as tunnels or overpasses that are prone to water accumulation. In response to this situation, it is necessary to establish a water level detection mechanism that is coordinated with weather forecasts to timely assess and report the road conditions in areas prone to water accumulation.

When the weather forecast predicts heavy rainfall, it is common to use a combination of manual and sensor methods, such as using pressure type water level gauges, ultrasonic water level gauges, and other sensor tools to measure and determine the depth of water level. At the same time, related technologies will also combine sensors with cameras to obtain visual information through the cameras, in order to assist in determining the water level on the road surface.

Based on the above scenario, sensors may encounter maintenance difficulties or low monitoring accuracy due to factors such as installation, weather, and lighting. The radar water level gauge based on millimeter wave technology has the advantages of non-contact measurement, large range, high accuracy, easy installation, and almost no environmental conditions such as external temperature and humidity, which effectively supplements the shortcomings of water level monitoring.
