The QJ‑JJ Series Digital Snow Depth Sensor adopts an ultrasonic measurement principle, enabling non‑contact and high‑precision snow depth detection. The sensor emits ultrasonic pulses and calculates snow depth by measuring the time difference between pulse emission and return. By compensating for changes in the speed of sound through air temperature measurement, it ensures accurate results and enables the automated and precise monitoring of snowfall processes.
Beyond its high‑accuracy performance, the sensor features low power consumption, dust‑ and sand‑resistance, maintenance‑free operation, and easy installation, ensuring long‑term stability even under complex environmental conditions. Designed specifically for extremely cold and corrosive environments, it is capable of continuously monitoring snow depth variations and snowfall amounts over different time periods, providing reliable data support for meteorological and environmental monitoring applications.
