SKS-3DC Integrated Wind Speed and Direction SensorDetailed product description：

SKS-3DC integrated wind speed and direction sensor is a new type of integrated wind speed and direction sensor. It is designed with a portable waterproof and shockproof structure, which can be used in the field all day long. It has high detection accuracy, low power consumption, environmental protection and energy-saving design. This instrument is widely used in fields such as environmental protection, meteorology, agriculture, forestry, water conservancy, construction, scientific research, and teaching.

2、 Product features:
1. The product structure is designed for outdoor work, with wind resistance, rain resistance, corrosion resistance, light aging resistance, and strong magnetic interference resistance, suitable for year-round use in the field.
2. Adopting an integrated structure, the wind speed and direction collection technology is combined into one, which is small in size, light in weight, and extremely convenient to carry and install in the field.
3. The shell is made of plastic grease material and molded by pressing, which is beautiful and sturdy. It is extremely easy to install and can be tested by hanging it anywhere.
The system adopts low-power design, digital processing technology, and high detection accuracy.
5. The wind vane has a red fluorescent surface, indicating a beautiful and clear appearance.

2、 The working principle of the photoelectric wind direction sensor is that the low inertia light metal wind vane responds to the wind direction and drives the coaxial encoder to rotate. This encoder encodes the Gray code and scans it with photoelectrons to output electrical signals corresponding to the wind direction. The photoelectric wind speed sensor adopts a low inertia lightweight material wind cup, which rotates with the wind and drives the coaxial cutting disc to rotate. It uses photoelectrons to scan and output a pulse train, and outputs the corresponding value of pulse frequency corresponding to the number of revolutions, which is convenient for signal acquisition and processing.
