Ultra-Low-Power Ultrasonic Anemometer | RS485 & NMEA-0183 Wind Speed Sensor
An ultra-low-power ultrasonic wind speed sensor designed for continuous outdoor monitoring with exceptional efficiency. Solid-state, maintenance-free operation with RS485 and NMEA-0183 outputs for seamless integration into weather, marine, and industrial systems.
This ultrasonic anemometer measures wind speed using time-of-flight ultrasonic technology, eliminating moving parts and mechanical wear. The redesigned acoustic path and firmware improve performance in rain and static installations, making it well suited to permanent weather stations and infrastructure monitoring.
Engineered for extreme efficiency, the sensor operates at sub-milliamp current draw at 5 V (typical sampling at 1 Hz), enabling long-term deployment in solar- and battery-powered systems. A robust mechanical design enhances durability and reliability in harsh outdoor environments.
Multiple industrial communication options are available, including RS485 and NMEA-0183, supporting straightforward integration with PLCs, RTUs, SCADA systems, data loggers, marine electronics, and IoT platforms.
