Mechanical Wind Speed and Direction Sensor (Anemometer) for Weather Stations and IoT Monitoring
RS485 Modbus Wind Sensor for Meteorological Observation, Smart Agriculture, and Environmental Monitoring Systems
Product Introduction
The KH.QX-2 Mechanical Wind Speed and Direction Sensor is a reliable anemometer designed for continuous measurement of wind speed and wind direction in meteorological, agricultural, hydrological, and environmental monitoring applications.
Based on a proven mechanical sensing principle, the sensor accurately detects wind speed through rotating cups and measures wind direction through a directional vane, converting mechanical movement into stable digital signals for real-time data acquisition.
With durable outdoor construction and RS485 Modbus RTU communication, the KH.QX-2 is suitable for integration into automatic weather stations, IoT monitoring networks, telemetry stations, and smart environmental management systems.
It provides reliable wind data for applications including weather observation, agricultural climate monitoring, irrigation management, environmental research, and outdoor monitoring networks.
How It Works
The sensor uses a mechanical cup anemometer and wind vane structure.
The rotating cups measure wind speed, while the directional vane detects wind direction. The measured signals are converted into digital data and transmitted through the communication interface.
This ensures:
- Continuous wind monitoring
- Stable outdoor operation
- Reliable real-time meteorological data
- Easy integration with monitoring systems
