Road Ice Sensor

1、Road Ice Sensor Product Introduction

Road Ice Sensor can accurately detect the thickness of ice, snow and water film on the road surface without being implanted in the road surface.Road Ice Sensor employs unique microwave detection technology and a multi-parameter fusion algorithm. It monitors the surface of the sensor—specifically detecting the output values corresponding to various material states and environmental conditions, such as ice formation, ice thickness, water accumulation, and temperature—and integrates temperature detection and compensation technologies to provide precise monitoring of icing conditions and ice thickness.

The sensor is capable of simultaneously outputting both icing pre-warning and alarm signals; it can also be paired with temperature and humidity sensors to facilitate comprehensive, multi-faceted environmental monitoring of road surfaces.

The online icing monitoring sensor consists of an electronic module—powered by MCU processing technology—and a sensing probe. A PT1000 platinum resistance element is embedded within the probe to provide temperature input to the sensor system.

Temperature compensation is achieved by utilizing the PT1000 sensor to acquire real-time temperature data; this temperature signal is then used to adjust the calibration curves within the MCU, thereby significantly enhancing the accuracy of ice detection.

Characterized by its simple structure, ease of installation, and strong anti-interference capabilities, this online road condition monitoring sensor is ideally suited for monitoring road icing on highways, airport runways, bridges, and urban roadways. It serves as a critical solution for various Internet of Things (IoT) applications, including intelligent transportation systems and smart city initiatives.
