Non Invasive Road Sensor

Non Invasive Road Sensor Product Introduction

Non Invasive Road Sensor uses infrared detection technology to accurately detect the thickness of ice, snow and water on road surfaces.The LM2 is a Non Invasive Road Sensor that uses remote sensing technology to avoid damage to the road and thus avoid traffic interference caused by the installation of road weather stations. Multi-spectral measurement technology enables accurate detection of the thickness of icy, snow and water on the surface of the road. In road conditions where the embedded pavement sensor is inconvenient or inaccessible, the LM2 detector is the ideal choice. Remote sensing installation means no need to close the road or cut the road surface, and the installation work is both safe and convenient. Low maintenance is an ideal choice for the composition of road meteorological systems. It can be installed on existing weather stations or on other buildings with unobstructed views of the road surface.

The LM2 detector is installed in an all-weather, durable housing to ensure that it can withstand severe weather, which allows it to provide accurate data in any weather conditions. By providing road surface condition information, the LM2 detector provides accurate monitoring data to the road management department and takes response measures before road safety risks occur. Rugged design, all-weather measurement
