Pengairan Lahan Pertanian Berdasarkan pada Kelembapan dan Suhu Tanah Berbasis IOT (Internet of Things) Menggunakan Nodemcu V3 Lolin

Abstract

Telah dirancang dan dipabrikasi sistem pengontrolan suhu ruangan. Pengairan lahan pertanian berdasarkan pada kelembapan dan suhu tanah berbasis internet, yang didalamnya terdapat sebuah sensor kelembapan YL-69 dan sensor suhu DS18B20. NODEMCU V3 LOLIN digunakan sebagai pengontrol, penerima dan pengolah data pada sistem otomatis pengatur suhu dan ruangan. Prinsip kerja alat, apabila suhu ≥ 28,9oC dan kelembapan ≤40, maka pompa akan hidup secara otomatis dan notifikasi dikirim melalui e-mail, dan apabila suhu ≤ 28.5oC, maka pompa akan mati secara otomatis dan notifikasi juga dikirim melalui e-mail. Secara keseluruhan kinerja alat yang dirancang sudah cukup baik, hal ini dapat dilihat dari hasil perhitungan rata rata persen deviasi yaitu 3 %.

The increasing number of people causes increasing food needs. Agriculture is the main source of food needs. In agriculture land irrigation is very influential on the results of plant growth. So that the water discharge needs to be considered so as not to overdo it and lack it. Water discharge that will have less effect on plant growth while excessive water discharge will affect the availability of water sources. Automation of irrigation systems is one of the most convenient, efficient and effective methods for optimizing water use. The system will help save water and make plants grow better because of controlled conditions. Certain humidity read by the humidity sensor will be the input system and the electric water pump will be the output of the NodeMCU.
