Road condition sensor, non-contact road condition detector, which uses remote sensing technology to avoid damage to the road, thus avoiding interference to traffic caused by the installation of road weather stations. Multispectral measurement technology enables accurate detection of the presence and thickness of ice, snow, and standing water on road surfaces, as well as real-time monitoring of weather phenomena such as heavy fog, rain, and snow that affect traffic safety.
1Road condition sensorProduct Introduction
The BK-LM1 series non-contact road surface condition detector adopts remote sensing technology to avoid damage to the road, thus avoiding interference to traffic caused by the installation of road weather stations. Multispectral measurement technology enables accurate detection of the presence and thickness of ice, snow, and standing water on road surfaces, as well as real-time monitoring of weather phenomena such as heavy fog, rain, and snow that affect traffic safety.
