Abstract

Pada penelitian ini telah dilakukan fabrikasi dan analisis Wind Sonic 3D dengan menggunakan metode waktu tempuh (time of flight) dan susunan sensor dual transduser. Jarak transduser (transmitter 1–receiver 1) pada tiap sumbu adalah 16 cm dan jarak antar transduser (transmitter 1-receiver 2 dan transmitter 2-receiver 1) adalah 3 mm dan 10 mm. Wind Sonic 3D mengunakan sensor ultrasonic 40 KHz. Proses kalibrasi sensor wind sonic dilakukan pada dua kondisi yaitu kondisi tanpa gangguan dan kondisi dengan kecepatan angin 2.3 m/s pada dua variasi jarak antar transduser. Pada jarak antar transduser 3 mm dengan keadaan tanpa gangguan range pengukuran yang diperoleh adalah -0.19 – 0.19 m/s dan keadaan kecepatan angin 2.3 m/s Selisih range pengukuran adalah -0.19 – 0.29 m/s dengan nilai persentase eror di antara 0-12.62 %. Pada jarak antara transduser 10 mm dengan keadaan tanpa gangguan range pengukuran yang diperoleh adalah 0 – 0.14 m/s dan keadaan kecepatan angin 2.3 m/s selisih range pengukuran adalah 0 – 0.21 m/s dengan nilai persentase eror pada sumbu X di antara 1.28% – 9.14%, sumbu Y di antara 0.29% – 8.61% dan sumbu Z di antara 0.05% – 7.44%. Berdasarkan hasil kalibrasi dapat diketahui bahwa untuk mengunakan susunan sensor dual transduser pada Wind Sonic 3D, jarak minimum antar transduser adalah 10 mm untuk mengurangi terjadinya interfrensi gelombang dan eror pengukuran. ======================================================================================================= In this research, Wind Sonic 3D fabrication and analysis have been carried out using the time of flight method and dual transducer sensor arrangement. The distance between the transducers (transmitter 1 – receiver 1) on each axis is 16 cm and the distance between the transducers (transmitter 1-receiver 2 and transmitter 2-receiver 1) is 3 mm and 10 mm. Wind sonic 3D uses a 40 kHz ultrasonic sensor. The wind sonic sensor calibration process is carried out in two conditions, namely conditions without interference and conditions with a wind speed of 2,3 m / s at two variations of the distance between the transducers. At the distance between the 3 mm transducer and the state without interference, the measurement range obtained is -0,19 – 0,19 m / s and the state of wind speed is 2,3 m / s. The difference in the measurement range is -0,19 – 0,29 m / s with a percentage error value between 0-12,62 %. At the distance between the transducer of 10 mm with a state without interference, the measurement range obtained is 0 – 0,14 m / s and the state of wind speed is 2,3 m / s the difference in the measurement range is 0 – 0,21 m / s with the percentage error value on the X-axis between 1,28% - 9,14%, Y-axis between 0,29% - 8,61% and Z-axis between 0,05% - 7,44%. Based on the results of the calibration, it can be seen that to use a dual transducer sensor arrangement in wind sonic 3D, the minimum distance between the transducers is 10 mm to reduce the occurrence of wave interference and measurement errors.
