Winter is coming. From meteorology to climate research to winter sports, snow layer depth is a critical parameter. Typically, snow depth sensors are based on either optical or acoustic measurement principles. There are arguments for both, it mainly depends on the respective application:

• Ultrasonic snow sensors rely on acoustic sensing. They are typically cheaper and energy-efficient.
• Laser-optical instruments provide the highest precision and resolution. They are maintenance-free and measure consistently regardless of the surrounding weather.
