PRODUCT DESCRIPTION
The TH-120-01H1 is an integrated ultrasonic wind speed and direction sensor designed for outdoor wind monitoring and meteorological data collection. It features a non-mechanical structure without external rotating parts. The product has a white cylindrical body, a round protective top cover, multiple support columns, and an open airflow channel in the middle, allowing it to detect airflow changes in the surrounding environment. It measures wind speed from 0 to 40 m/s (0.1 m/s resolution, ±3% accuracy) and wind direction from 0 to 359° (1° resolution, ±3° accuracy).
With a compact and clean structural design, the sensor is suitable for installation on weather stations, environmental monitoring equipment, agricultural monitoring systems, and outdoor automation platforms. Compared with traditional mechanical wind sensors, the ultrasonic structure reduces the need for external rotating components such as wind cups or wind vanes, making it suitable for long-term outdoor monitoring projects that require stable operation and lower maintenance. Rated IP65 and built for -50 to +80°C and 0–100% RH, it runs on DC 12–24 V and connects via RS232, RS485, or SDI-12 with Modbus-RTU protocol. It can work with data loggers, controllers, or integrated weather monitoring systems to provide data support for wind speed and direction monitoring, environmental analysis, and equipment control.
