| 總結: | The wind is one of the main components of weather, therefore the wind is
often become an interesting research subject especially focus on its speed. The
purpose of this research is to apply optocoupler sensor for detecting wind speed
and direction. Optocoupler sensor is used to read the perforated disc which
connected with three wind catcher.
The data of wind speed and direction are obtained from digital calculation
of a rotating perforated disc. Every wind gusts, the holey mechanical disc will
rotate and cause changes in the sensor optocoupler logic. The logic changes are
then processed by a microcontroller into the data of wind speed and direction.
This monitoring tool use optocoupler sensor, microcontroller ATmega8 as
processor, LM35 as temperature gauges, TLP and RLP 433 module as transmitter
and receiver data. Afterwards the measurement results will be displayed in the
computer as unit viewer.
Based on the observation and calculation, the testing of hardware shows
wind direction error is 1.5 degrees, wind speed error at 0.27 km/hour, and
temperature error at 0.7 degree. The distribution data obtained from the
observations indicate that the data collected from this tool fit with the regression
line, it can be interpreted that the data from observational identic with the data
from reference tool, or can be concluded that this tool has a high precision. |
