Overview

The SnowVUE™10 is a digital, ultrasonic snow-depth sensor that provides continuous and accurate snow-depth measurements with its advanced spectrum analysis and best-in-class, wide-band transducer. With its low-power requirement and low-maintenance design, the SnowVUE 10 is suitable for most alpine and remote installations. The SnowVUE 10 also features Campbell Scientific’s total uptime diagnostic package to provide you with critical sensor performance measurements such as internal humidity, temperature, sensor level (tilt), measurement quality, and incoming voltage. An external air temperature sensor is required to correct for the changes in sound velocity due to changes in temperature.

Technical Description

The SnowVUE™10 uses a wide-band, ultrasonic transducer to create sound pulses that are reflected off the snow surface. By measuring the two-way travel time of the pulse, the distance to the snow surface can be precisely calculated using advanced spectrum analysis. Because the speed of sound through air varies with the air temperature, an accurate air temperature measurement is required to correct for this change.

SnowVUE Program Example for GRANITE-Series, CR6, CR1000X Dataloggers v.1 (10 KB) 03-11-2021

Two programs that read the SnowVUE 10 sensor. One program performs temperature compensation to provide snow depth. The other program uses extended commands to send the air temperature and distance to ground to the sensor and the sensor calculates the snow depth. Both example programs are compatible with the GRANITE-series, CR6, and CR1000X dataloggers.
