Abstract

The wind tunnel development with wind speed control is presented in this paper using an ultrasonic anemometer. It were used the Time Difference and Phase Difference methods in the measurement of the air speed, and the circuit used for the measurement as for the speed control it was based on a microcontroller and an motor (fan). The experimental results obtained from the proposed circuit are compared with a commercial anemometer. The analysis of temporal response performance of the fan speed control circuit was developed to validate the proposed system.
