Aluminium Wind Direction Sensor – 3S-WD-A
The Wind Direction Sensor is a professional meteorological device designed to measure horizontal wind direction. It uses a Hall Effect Position Sensor to detect changes in wind direction and converts them into a signal. The measured data is transmitted as an analog output signal (0-3.3V). This model can connect to SEVEN’s Irradiance Sensor, Sensor Box, and Compact Weather Station models via a pin connector.
It should be remembered that, depending on the location and circumstances, solar cells should be set at specific tilt angles (angles to the earth) in order to maximize their effectiveness. Consequently, variations in the convection coefficient are also caused by the wind acting on the array’s plane at various angles and orientations. This is because winds from different directions have distinct characteristics at different sites, therefore the effective area varies depending on the wind direction. Because of this, SEVEN wind direction sensors are crucial for assessing power plant performance where different wind directions are significant.
A professional meteorological tool for determining the horizontal wind direction is the Aluminium Wind Direction Sensor. It detects and transforms changes in wind direction into a signal using a Hall Effect Position Sensor. The analog output signal (0-3.3V) is used to convey the measured data. A pin connector allows this model to be connected to SEVEN’s Irradiance Sensor, Sensor Box, and Compact Weather Station products.
