ToltHawk™ Snow Depth Monitor
Reliable snow depth data—without touching the snow.
ToltHawk transforms roadside infrastructure into an intelligent, always-on snow monitoring station. Mounted above the roadway and powered entirely by solar energy, the ToltHawk snow sensor uses advanced radar technology to continuously measure snow depth without any moving parts or ground contact.
By looking downward from a fixed height, ToltHawk precisely measures the distance to the snow surface and automatically calculates snow accumulation in real time. As snow builds up—or melts away—the system captures accurate, repeatable depth measurements, even during active snowfall, nighttime conditions, or low visibility.
Built for Roadside Winter Conditions
- Non-contact radar sensing
Measures snow depth without probes, stakes, or pressure plates that can freeze, shift, or fail. - All-weather operation
Radar performs reliably in blowing snow, fog, darkness, and extreme cold. - Solar powered & self-contained
No trenching, no external power, no seasonal redeployment. - Low-maintenance design
No moving parts, no heaters required, and fully sealed electronics for winter durability.
Smarter Decisions for Winter Operations
Installed along highways, mountain passes, bridges, and critical corridors, ToltHawk provides transportation agencies and maintenance teams with objective snow depth data to support:
- Plow dispatch optimization
- Anti-icing and de-icing decisions
- Avalanche and drift monitoring zones
- Performance verification of winter maintenance activities
Data is wirelessly transmitted to ToltHawk Cloud Services, where snow depth trends can be viewed in real time on a web browser or mobile device—alongside other environmental measurements if needed.
Designed for Real-World Deployment
With a compact footprint and simple pole-mount installation, ToltHawk can be deployed quickly using existing roadside structures. A defined ground reference ensures consistent, long-term measurements from the first snowfall through spring melt.
ToltHawk brings modern sensing to winter road management—quietly, passively, and reliably.
