Road Weather Information Systems

(RWIS)

About RWIS Products

High Sierra Electronics, Inc. is a leader in bringing new sensors and monitoring technology to the Road Weather market. Our RWIS products are state-of-the-art for fixed and mobile road weather applications.

Our IceSight product line measures road conditions for warnings and plowing operations. The fixed unit mounts on a pole near the roadway and the mobile unit (Mobile IceSight) mounts to a vehicle.

Our Surface Sentinel product line provide surface temperature and air temperature, in real-time, from a fixed location or from a vehicle (Mobile Surface Sentinel). The Surface Sentinel is a low cost way to supplement any RWIS network.

All of High Sierra Electronics’ RWIS products are designed for the high demands of road weather management professionals.
