Design and fabrication of a novel wind sensor for volume constrained applications

In this study, a new wind sensor design and production for volume-constrained applications have been carried out. The developed sensor uses two ultrasonic transceivers and four NTC thermistors to measure wind speed and direction. Ultrasonic transducers measure wind speed more accurately and quickly, while four NTC thermistors temperature differences were used to determine wind direction accurately. In tests conducted within the range of 1 m/s to 5 m/s, the average error rate between the sensor's measured wind speed and the actual speed remained around 2.5%, indicating that the sensor has good accuracy. Additionally, the minimum wind speed measured by the sensor was determined to be 0.6 m/s. Wind direction measurements were also made accurately, with consistent results between the actual direction and the calculated direction. Environmental factors have a significant impact on the sensor's accuracy. An increase in humidity caused a noticeable decrease in accuracy. Temperature changes similarly affected the sensor's accuracy. This sensor design provides an ideal solution for volume-constrained areas by offering low cost, maintenance-free operation, and long lifespan. Energy efficiency is also advantageous for long-term use. This study presents an alternative approach to existing wind measurement systems and lays the foundation for future research.
