Vasthi’s outdoor weather station measures wind speed and direction, air temperature, barometric pressure, and relative humidity. The wind measurement is performed using ultrasonic sensors, which means there are no moving parts to wear out or get caught in the rigging.
The WSO100 accurately measures wind speed and direction even when tilted, making it ideally suited for heeled sailboats or powerboats operating in pitching and rolling seaways.
When used with Vasthi displays DSM 150, DSM 250 N2KView, you can view apparent wind speed and direction, humidity, air temperature, barometric pressure (with graphs to see trends), wind chill factor, heat index, and dew point. If you add speed through water (DST110), GPS (GPS200), and compass (SSC300), you can view actual vessel-referenced wind speed and direction as well as ground-referenced speed and direction.

It’s an advanced weather monitoring system that uses ultrasonic sensors to accurately measure environmental parameters such as wind speed, wind direction, temperature, humidity, and atmospheric pressure.
Ultrasonic sensors measure the time of flight of sound waves between transducers to calculate wind speed and direction without moving parts, resulting in high accuracy and reliability.
This station typically measures wind speed, wind direction, temperature, humidity, pressure, and optionally rainfall and solar radiation depending on configuration.
Yes — it’s designed for rugged outdoor use with weather-proof construction for environments like urban areas, industrial sites, airports, and research stations.
Absolutely — it supports remote connectivity and data output via standard interfaces (like RS-485, Ethernet, Modbus) for integration with servers, dashboards, and SCADA systems.
