Abstract

Penelitian ini merancang bangun alat transmisi temperatur gunung api menggunakan sistem telemetri nirkabel sensor berbasis Arduino Uno R3. Perangkat keras sistem ini terdiri dari satu unit transmitter yang dilengkapi oleh sensor LM35 dan satu unit receiver yang terhubung dengan pemograman LabView pada PC. Semua unit dikendalikan dengan menggunakan Arduino Uno R3. Data temperatur dikirim oleh unit transmitter ke unit receiver menggunakan transceiver nRF24L01+ yang memanfaatkan gelombang radio sebagai media pengiriman. Hasil pengujian sensor LM35 meperlihatkan bahwa hubungan antara tegangan keluaran sensor dengan temperatur adalah linear dengan nilai koefisien korelasi sebesar 0,9987. Pengujian transceiver nRF24L01+ pada kondisi tanpap enghalang atau line of sight (LOS) diperoleh jarak maksimum sebesar 1,1 km. Pengujian transceiver nRF24L01+ pada kondisi dengan penghalang atau non line of sight (NLOS) pada posisi datar diperoleh jarak maksimum 258 m. Pada posisi tak datar transceiver nRF24L01+ bekerja maksimum pada sudut kemiringan sebesar 7,30° yaitu dengan jarak transmisi 329,67 m. Pada sudut kemiringan lebih besar dari 7,30° maka jarak transmisi akan berkurang.
