Octopus Wind Speed Sensor Anemometer Three Aluminium Cups

This is a wind speed sensor with rain-proof design. It has a standard connector for Octopus brick series’ products. We can use it to test wind speed. It adopts three half sphere bowls with 6CM diameter, presenting 120 degrees branch installation. Under the effect of wind power, it can spin. Higher wind speed, faster it rotates. When wind spinning component rotates with a diameter about 20Cm, it will force a mini DC motor to generate DC voltage. Higher wind speed will generate higher DC voltage. Its maximum voltage generated can reach 1.2V. You can refer to the attched parameter form in the behind for actual wind speed and voltage output parameter. Its tolerance is about 10%.
