This RS485 Wind Speed Transmitter is a professional meteorological sensor designed to accurately measure horizontal wind speed in the range of 0 to 32.4 m/s. As a high-precision RS485 wind speed sensor, it functions as a reliable anemometer for real-time data logging. It features an integrated Hall sensor and is constructed using precision die-cast aluminum alloy, ensuring small dimension tolerance, high surface accuracy, and durability in harsh environments. The internal circuitry of this wind speed meter is fully protected for weather resistance, anti-corrosion, and waterproof performance, while the external connector uses a military-grade corrosion-resistant plug for extended product life in any professional weather station setup.

The sensor adopts a low-inertia anemometer that efficiently converts wind into rotational motion, which is then translated into accurate digital signals via the internal Hall sensor. This RS485 wind speed sensor anemometer provides stable Modbus RTU communication for industrial integration. Its compact structure, ease of installation, and long transmission range make it suitable for a wide variety of applications including meteorology, environmental monitoring, oceanography, agriculture, transportation, and industrial automation. Whether you need a wind speed transmitter for remote monitoring or a wind speed meter for local control, this DFRobot sensor delivers industrial-grade performance.
