Airmar 300WX NMEA 0183/2000 RS422 WeatherStation

The Airmar 300WX WeatherStation is a professional-grade sensor designed for accurate wind measurement on moving platforms. It combines GNSS, a 3-axis compass, and motion sensing to provide dynamic true wind data for various applications including agriculture, marine, and autonomous vehicles. The 300WX-IP67 variant offers enhanced durability with a fully sealed, water- and dust-resistant housing for harsh environments.

Features:

• Utilizes ultrasonic technology with no moving parts to ensure maintenance-free and reliable operation in all conditions
• Integrates seamlessly with heavy equipment using J1939 and ISOBUS protocols with automatic baud rate detection (250/500 kbps) for flexible connectivity
• Provides wireless Bluetooth access for easy configuration, calibration, and firmware updates via a mobile app without dismounting
• Delivers comprehensive environmental data including wind speed, direction, temperature, humidity, barometric pressure, and motion sensing
• Calculates Dynamic True wind by compensating for vehicle motion using GNSS and stabilized compass inputs for precise readings
• Supports real-time data output to enhance navigation, autonomous control, and performance optimization across diverse platforms
• 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
