Introduction
The XF-CQ11 road condition sensor utilizes infrared laser remote sensing technology, which avoids damaging the road surface and thus prevents traffic disruptions caused by the installation of road weather stations. By analyzing the infrared spectral characteristics of water, ice, and snow, this non-contact road condition sensor provides real-time data on the actual road surface conditions, measures the type and thickness of water, ice, and snow coverage, and calculates the corresponding coefficient of friction.
Structure
- Receiving lens
Used to collect the reflected infrared signals from the road surface and transmit them to the internal detection module for analysis, ensuring accurate identification of road surface conditions. - Measuring Laser
Emits infrared laser beams toward the road surface to analyze the spectral characteristics of water, ice, and snow, enabling the sensor to determine the type and thickness of surface coverage. - Positioning Laser
Helps accurately indicate the measurement area on the road surface, ensuring that the sensor detects the correct monitoring point and improving measurement reliability. - Infrared Temperature Probe
Measures the surface temperature of the road using infrared technology, providing essential data for identifying freezing conditions and evaluating road safety. - Sensor Rain Shield
Protects the sensor components from rain, snow, and direct sunlight, ensuring stable operation and improving the durability and reliability of the sensor in outdoor environments.
Working Principle road condition sensor
The XF-CQ11 road condition sensor provides real-time data on the actual condition of the road surface, measuring the type and thickness of water, ice, and snow coverage, and calculating the corresponding slip coefficient. This non-contact sensor features an infrared emitter aimed at a selected location on the road surface; light emitted from the sensor is reflected back to the receiver for processing and calculation. The sensor detects the thickness of water, snow, or ice by distinguishing the specific wavelengths reflected from the road surface caused by each of these elements.
Adverse weather conditions such as rain, snow, and freezing temperatures can reduce the road surface friction coefficient, thereby adversely affecting traffic flow and driving safety. The non-contact road condition sensor establishes a practical “slipperiness” index that indicates the current road surface’s skid resistance; a higher value indicates better skid resistance. The sensor can quickly detect the current road surface’s skid resistance and alert users to road safety hazards.

Installation Method
The XF-CQ11 road surface condition sensor can be installed at the roadside, facing the road surface at a horizontal angle of 30 degrees or greater. It can also be installed above the road, such as on bridges or traffic signal structures. Traffic flow at the measurement location does not affect the measurement, unless a vehicle comes to a complete stop at that location for several minutes.
