Abstract :
The research was conducted to determine the accuracy of the wind speed
sensor in a microcontroller-based wind tunnel. In aerodynamics, a wind tunnel is
a tool used to study the effects of air moving through solid objects. The testing
proccess in this study uses 2 variations, testing on the manufacturer?s anemometer
and the design anemometer by comparing the engine rotation value (Rpm) obtained
from the two tools. The result of the research is that the level of accuracy of the
designed wind speed sensor is quite accurate compared to the manufacturer?s speed
sensor.
