• Calculated dew point and heat index
• GNSS position speed over ground and course over ground
• Three-axis solid-state compass with dynamic stabilization
• Three-axis rate gyro supplies rate-of–turn data
• Three-axis accelerometer for best-in-class pitch and roll information
• Housing IP64 rated for dust/water-ingress protection
• Enhanced wind speed accuracy: 1.5 knots RMS at 20 knots
• Bluetooth wireless connectivity for use with Airmar’s CAST app to view data configure sensors and perform firmware updates
• Automatic baud rate detection for J1939 and ISOBUS (250 kbps / 500 kbps)

Weather data is only valuable if it's accurate in the moment you need it.

The new 300WX WeatherStation from Airmar is engineered for professionals who operate in motion — agricultural operators autonomous vehicle designers marine integrators and industrial system builders who can’t afford uncertainty.

Unlike traditional wind sensors Airmar WeatherStations deliver accurate wind speed and direction from moving vehicles. By combining GNSS positioning a stabilized 3-axis compass and motion sensing they continuously correct apparent wind caused by movement to deliver calculated Dynamic True wind speed and direction. Whether mounted on an agricultural sprayer sailboat weather vehicle or autonomous platform the wind data remains accurate — even while you’re moving.

Designed for Modern Equipment Integration - The 300WX was built with today’s machinery in mind. With added J1939 and ISOBUS outputs and automatic baud-rate detection it integrates seamlessly into agricultural and heavy-equipment systems. Installation is simple. Compatibility with a wide range of systems is proven. Integration headaches are reduced.

Built to Work Not to Be Serviced - Mechanical sensors fail. Wind cups break. Vanes wear out. The 300WX never does—ultrasonic technology means no moving parts no maintenance no downtime.

Install it once. Rely on it every day - Wireless Bluetooth connectivity to Airmar’s CAST app allows configuration calibration and firmware updates without removing the instrument from its mounted location. No pulling equipment out of service. Just fast secure updates from a mobile device.

A Complete Environmental Picture - In a single compact instrument the 300WX provides a holistic view of environmental conditions — wind speed and direction temperature barometric pressure relative humidity heat index and wind chill vessel or vehicle motion and GNSS positioning. It measures both the weather around you and the motion of the platform beneath it. That context is what transforms raw data into operational intelligence.
