Rancang Bangun Alat Pengering Kopi Mengunakan Kontrol Suhu Berbasis Arduino Uno

Abstract

A coffee dryer design has been made using temperature control based on Arduino Uno. This tool is made as a coffee dryer automatically without drying in the sun. As for the components used in designing this tool, such as Arduino, heater, fan, LM 35 temperature sensor, and relays. therefore the author designed this automatic coffee dryer, to make it easier for farmers to carry out the drying process. This tool is able to shorten the drying time. The method used in designing this coffee dryer is based on Arduino which can dry briefly. Dry coffee, within 3-5 hours. From research conducted this tool is effective in the coffee drying process compared to the help of sunlight.
