Abstract

Sebuah alat pengukur kecepatan angin saat ini hanya dapat membaca kecepatan angin tanpa mengetahui jenis angin pada saat pengukuran. Untuk itu, alat pengukur kecepatan angin akan diperbarui dengan tambahan fitur yang dapat membaca jenis angin. Pada alat ini juga ditambahakan sensor wind vane untuk mendeteksi kemana arah angin berhembus. Alat ukur kecepatan angin akan dibuat menggunakan anemometer cup yang dipasang sensor optocoupler sebagai pengkonversi gerak putar menjadi kecepatan angin dan arah angin menggunakan wind vane yang dipasang sensor hall effect untuk menentukan arah angin bertiup. Pengujian anemometer cup dan wind vane dilakukan dengan memberikan input berupa kecepatan angin. Angin akan menggerakkan cup dan memutar piringan berkisi yang dibaca oleh sensor optocoupler. Angin akan menggerakkan wind vane sesuai arah hembusan sehingga apabila magnet yang berada di bawah wind vane sejajar dengan sensor hall effect akan mempengaruhi tegangan pada hall effect (low). Output tegangan tersebut akan diolah oleh mikrokontroler ESP32 dan dikirim ke website sehingga dapat ditampilkan kecepatan, jenis dan arah anginnya. Hasil pengujian alat menunjukkan bahwa sensor wind vane dapat membaca arah angin pada saat itu dengan koreksi 0 dengan tingkat akurasi 100%, range pengukuran 0o – 315o, span 315o, resolusi 45o dan sensitivitas 0,14, yang berarti sensor dapat dikatakan valid dan bisa digunakan dalam sebuah penelitian. Pembacaan sensor anemometer cup memiliki rata-rata eror sebesar 2,007% yang berarti tingkat eror <3% dan memiliki tingkat akurasi sebesar 97,93%, range pengukuran 0 – 40,72 m/s, span 40,72, resolusi 0,01 m/s, dan sensitivitas 0,00024, sehingga dapat dianalisa bahwa sensor anemometer ini sudah cukup akurat. Untuk uji database didapat bahwa database dapat menampilkan data pembacaan sensor pada tanggal 3 Mei 2023 pada pukul 13.35 hingga pukul 14.00. Kemudian untuk pengujian pengiriman data pada pukul 08.00 – 10.00, pukul 12.30 – 14.00, dan pukul 19.00 – 22.55 didapat bahwa pengiriman data sudah realtime dengan kecepatan pengiirman <1 detik, dan untuk pengujian GUI didapat bahwa GUI dapat menampilkan menu-menu serta data dari sensor.

A current wind speed meter can only read wind speed without knowing the type of wind at the time of measurement. For this reason, the wind speed meter will be updated with additional features that can read the type of wind. This tool also adds a wind vane sensor to detect which direction the wind is blowing. The wind speed measuring instrument will be made using an anemometer cup fitted with an optocoupler sensor to convert rotary motion into wind speed and wind direction using a wind vane mounted with a hall effect sensor to determine the direction the wind is blowing. Testing the cup and wind vane anemometers is carried out by providing input in the form of wind speed. The wind will move the cup and rotate the lattice plate which is read by the optocoupler sensor. The wind will move the wind vane according to the direction of blowing so that if the magnet under the wind vane is aligned with the hall effect sensor it will affect the voltage on the hall effect (low). The output voltage will be processed by the ESP32 microcontroller and sent to the website so that the wind speed, type, and direction can be displayed. The test results show that the wind vane sensor can read the wind direction at that time with a correction of 0 with an accuracy rate of 100%, measurement range of 0o – 315o, span of 315o, resolution of 45o, and sensitivity of 0.14, which means the sensor can be said to be valid and can be used in a study. The cup anemometer sensor reading has an average error of 2.007%, which means the error level is <3% and has an accuracy rate of 97.93%, the measurement range is 0 – 40.72 m/s, the span is 40.72, the resolution is 0.01 m /s, and a sensitivity of 0.00024, so that it can be analyzed that this anemometer sensor is quite accurate. For the database test, it was found that the database can display sensor reading data on May 3, 2023, from 13.35 to 14.00. Then for testing data transmission at 08.00 - 10.00, 12.30 - 14.00, and 19.00 - 22.55, it was found that data transmission was real-time with sending speed <1 second, and for GUI testing it was found that the GUI can display menus as well as data from sensors
