Abstract

Telah dilakukan rancang bangun sistem monitoring kelembaban tanah menggunakan wireless sensor berbasis Arduino Uno. Rancangan perangkat keras sistem ini terdiri dari satu unit transmitter yang dilengkapi oleh sensor soil moisture SEN0114 V2 dan satu unit receiver. Semua unit dikendalikan dengan menggunakan Arduino Uno. Data kelembaban tanah dikirim oleh unit transmitter  ke unit receiver menggunakan transceiver nRF24L01+ yang memanfaatkan gelombang radio sebagai media pengiriman. Hasil deteksi nilai kelembaban tanah pada sensor ditampilkan oleh LCD 2x16 karakter. Hasil pengujian sensor kelembaban tanah meperlihatkan bahwa hubungan antara tegangan keluaran sensor dengan kelembaban tanah pada moisture meter adalah linear dengan nilai regresi sebesar 0,9758. Berdasarkan pengujian transceiver, jarak terjauh pengiriman data yang dapat diterima oleh receiver di luar ruangan tanpa ada penghalang adalah 200,1 m. Pada pengujian variasi sudut pengiriman, data dapat diterima oleh unit receiver pada sudut ³ 26,56â°. Apabila sudut lebih kecil dari 26,56â° data masih dapat diterima dengan adanya delay hingga sudut 11,31â°.

Kata kunci: sensor soil moisture, kelembaban tanah, wireless, gelombang radio, nRF24L01+
