Abstract

Telah dirancang bangun sebuah alat ukur kelajuan dan arah angin menggunakan sistem telemetri nirkabel. Sistem terdiri dari dua unit yaitu transmitter dan receiver. Unit transmitter berfungsi sebagai pengukur nilai kelajuan dan arah angin menggunakan sensor optocoupler ITR9608-F yang terdapat pada modul FC-03. Data nilai kelajuan dan arah angin ditransmisikan oleh transceiver nRF24L01+ yang memanfaatkan gelombang elektromagnet pada frekuensi gelombang radio 2,4 GHz. Data akan diterima oleh transceiver nRF24L01+ di unit receiver lalu ditampilkan pada LCD (Liquid Crystal Display). Hasil penelitian menunjukkan bahwa sistem telemetri nirkabel mampu mentransmisikan data dengan jangkauan maksimum 1000 m dengan kondisi tanpa penghalang, 650 m dengan kodisi ada penghalang saat cuaca cerah, dan 485 m dengan kondisi ada penghalang saat cuaca hujan 485 m. Persentase kesalahan rata-rata alat ukur kelajuan angin ini dihitung dan dibandingkan dengan beberapa alat acuan, 4,54 % dengan anemometer Lutron AM-4206 dan 7,65 % dengan anemometer mangkuk milik BMKG Stasiun Meteorologi Kelas II BIM Padang Pariaman. Alat ukur arah angin menampilkan delapan arah mata angin dengan sudut sebesar 45o. Alat ukur arah angin berhasil mendeteksi dan menampilkan arah angin yang sama dengan anemometer mangkuk milik BMKG.

Kata kunci: telemetri nirkabel, transceiver nRF24L01+, kelajuan angin, arah angin
