Alat Ukur Kelembapan Ph dan Suhu Tanah Mengunakan Sensor Ds18b20 dan Sensor Ph Berbasis Mikrokontroler Arduino Nano

Abstract

Corn is one of the most important carbohydrate-producing food crops in the world, apart from wheat and rice. The appeal of this corn plant is that it contains a variety of nutrients, one of which is protein, carbohydrates, fiber, and vitamins. Corn plants can grow and produce well in areas that have climatic conditions of air temperature, for tropical plants it is between 15-40°C and the air temperature needed for corn plants to develop properly ranges from 21-28°C.One of the corn producers in North Sumatra is Sipang Bolon, Simalungun Regency. For this reason, a tool is needed to measure temperature, humidity and pH on corn plant media using a DS18B20 sensor, humidity and pH sensor. This research can work to represent instruments for measuring temperature, humidity and soil pH in corn plants but at a lower cost, lower power consumption but still accurate and precise with calibrated sensors. Parameters observed were temperature, humidity and soil pH.
