Compact, reliable and cost-efficient – Accurate measurement of snow depth / snow height sensor SHM30 based on an opto-electronic distance sensor / laser rangefinder technology.

Compact, reliable and cost-efficient. The SHM30 snow depth sensor reliably determines snow depths up to 10 meter within seconds and with millimeter precision. Based on an opto-electronic distance sensor emitting visible eye-safe laser light (laser rangefinder), the SHM 30 allows probing distances up to 30 meter to detect the surface level. Unlike snow depth sensors using ultrasonic methods, the laser distance measuring technique is independent of temperature changes. Even if the measuring process is impaired by precipitation, the SHM 30 reliably finds the snow surface due to its mode of operation. Further evaluation of the transmitted signal strength allows discrimination between snow and grass.
