Wind speed measurement with a low-cost polymer optical fiber anemometer based on Fresnel reflection

Abstract

This study designed and experimentally verified a simple and low-cost anemometer based on Fresnel reflection using Polymer Optical Fiber (POF). The system was developed especially for wind speed measurement in harsh environmental conditions such as high electromagnetic interference. System verification was performed using a controlled wind source and a high-standard anemometer. In measurements made under normal temperature conditions, the dynamic range of the anemometer is between 3 m/s and 15 m/s. Experiments were carried out with two propellers of different diameters to evaluate the propeller diameter effect. According to the results obtained from the wind speed measurement experiments, it was observed that the mean error value for all measurements was 0.16, and the mean percentage relative error value was 1.85%.
