Özet
Traditional wind sensors, such as cup, hot wire, ultrasonic, and laser Doppler anemometers, often have mechanical parts that limit sensitivity, accuracy, and durability, unlike thermal flow sensors, which detect the wind by measuring the temperature variations using a heater. In addition, the methods reported in the literature have different advantages and disadvantages. In this study, different thermal flow sensor designs reported in the literature are examined and a new method based on the 2-dimensional NTC thermistor is proposed. Simulation results of the proposed method are presented. According to the results actual and calculated wind speed measurements well matched and the maximum wind speed error observed is less than %3. In addition, a simple testbed is presented for wind direction measurement.
