1. Overview of laser snow thickness sensor
Laser snow thickness sensor is also called laser snow depth sensor and laser snow depth monitor. The laser snow thickness sensor can be used to measure snow thickness with millimeter-level precision under all weather conditions. It is a digital snow thickness measurement instrument with high measurement accuracy, Stable and reliable work, simple operation and so on. Water is the foundation of all kinds of life on earth. The changes and movements of water have created our world today. Snowfall is an important part of the water cycle. Snowfall has a certain impact on the balanced development of the ecological environment and people's life and production.
The automatic snow depth monitoring station is a set of professional equipment for real-time monitoring of snowfall information launched by our company based on years of experience in manufacturing meteorological and environmental instruments. The equipment uses laser recognition and measurement technology for snow to overcome ultrasonic, electromagnetic wave, weight and other types The sensor cannot identify the shortcomings of snow, so as to achieve extremely high detection accuracy. By monitoring the distance of the location, the thickness of the snow can be obtained, and the snowfall per unit time can be analyzed. The device can be used as an independent automatic snow depth monitoring and alarm system, and can also be networked to form a diversified network monitoring.
Scope of application: Widely used in weather stations, port safety monitoring, road traffic safety monitoring, aviation monitoring, building safety monitoring, agricultural production monitoring, hydrology and water conservancy and many other fields.
2. Laser distance measurement principle of laser snow thickness sensor
The snow depth sensor uses the principle of phase laser range finder to measure the snow depth. The wavelength of the modulated light is converted to the distance represented by this phase delay. That is to use an indirect method to measure the time required for the light to go back and forth through the survey line, so as to solve the snow depth.

Remark:
For different measurement targets and measurement environments, due to excessive ambient light intensity, high or low ambient temperature, weak or strong reflection of the target, or rough and uneven surface of the target, the measurement range may be shortened or the measurement results may be affected. big error.
working principle:
measurement method:
Zero adjustment is required after the first installation or after moving the installation position. Press and hold "SET" for 5 seconds to complete the zero adjustment.
The working principle of the sensor: when there is snow (snow depth greater than 10mm), the data is collected once every 10 minutes; when there is no snow, the data is collected once every 30 minutes.
Heating time in the cavity: When the temperature in the cavity is lower than 0 degrees, turn on the heating mode and heat for 5 minutes each time.
