Snow Depth Measurement

Snow depth sensors measure snowpack depth and new snowfall for avalanche forecasting, water supply monitoring, road maintenance and ski resort operations. The R.M. Young SNOdar uses LIDAR to provide accurate, real-time snow depth readings, even during winter storms.


Model 54000 SNOdar Snow Depth Sensor

R.M. Young
The SNOdar is a highly accurate, reliable snow depth sensor designed to deliver real-time data—even in the middle of a snowstorm! Its mobile app makes setup effortless while providing instant access to live snow depth measurements from anywhere in the world.

The SNOdar is renowned for its accurate and robust monitoring of snow depth and new snowfall, even during winter storm events. It is one of the only snow depth sensors that utilizes LIDAR (Light Detection and Ranging) technology to provide accurate snow depth measurements. This high-precision method allows the SNOdar to create detailed, real-time snow depth data, ensuring reliable and efficient snow monitoring for a variety of applications. For added convenience, the SNOdar mobile app allows quick configuration, real-time monitoring via Bluetooth, and easy data downloads directly to your device.

The SNOdar transmits data via RS-232 or SDI-12 to a range of commercially available telemetry systems, including Satcom, data loggers, and cell modems. It also features an internal, non-volatile data logger capable of storing an entire season's worth of data, eliminating the need for separate data loggers for each sensor—resulting in significant cost savings during deployment. Its compact, lightweight design is built to withstand temperatures of -40°C and below. It runs on a 12 VDC battery, averaging less than 0.5 W of power, with a small battery and solar panel (e.g., 50Ah + 10W) sufficient for seasonal deployment. Easily configurable as a distance sensor, stormboard snowfall sensor, or seasonal snow depth sensor.
