KH.QX-2 Mechanical Wind Speed and Wind Direction Sensor | RS485 MODBUS Weather Monitoring
Product Introduction
The KH.QX-2 Mechanical Wind Speed and Wind Direction Sensor is a durable and cost-effective instrument designed for real-time wind monitoring. Using a proven mechanical measurement principle, it converts rotational and directional motion into electrical signals to provide accurate wind speed and direction data. With strong weather resistance and RS485 MODBUS communication, it is widely used in meteorological stations, transportation safety monitoring, agriculture, industrial ventilation, and smart environmental systems.
Key Features
• High reliability mechanical sensing: Mature measurement structure ensures stable and accurate performance under all-weather conditions.
• Cost-effective solution: Lower operating cost compared to ultrasonic or radar sensors while maintaining high measurement precision.
• Easy installation and maintenance: Simple mechanical structure supports fast setup and convenient field maintenance.
• Durable outdoor construction: Polymer engineering plastic housing resists UV exposure, corrosion, and mechanical impact.
• Flexible data transmission: Standard RS485 output compatible with MODBUS protocol for seamless integration into weather stations and IoT systems.
• Fast response rate: Supports 0.5-second data update interval for real-time wind monitoring.
Application Scenarios
• Automatic weather stations
• Environmental and meteorological monitoring networks
• Highway, bridge, and tunnel safety monitoring
• Agricultural climate and irrigation systems
• Airport and marine meteorological stations
• Industrial ventilation and building monitoring
