RANCANG BANGUN SISTEM PENGENDALIAN SUHU DAN KELEMBABAN PADA BOX PENYIMPANAN PRODUK BERBAHAN KULIT BERBASIS MIKROKONTROLLER ARDUINO UNO

Abstract

Fashion items in the form of leather products have good quality and are relatively expensive. Extra care is needed to maintain quality so that there is no damage in the form of skin cracks or faded paint color due to the influence of extreme temperatures and high humidity which can cause fungus in leather-based products. The storage area for leather products is also important, especially in a tropical climate like Indonesia. Ensure that the temperature and humidity in the room for storage of leather products conform to the parameters, namely temperatures between 21 ° C - 25 ° C and humidity  between  50%  -  70%.  The  use  of  storage  boxes  can  be  an  alternative  in  the  care  and storage of leather products which do not take up much space. Design the box using the Arduino Uno  microcontroller  as  controlling  the  system.  DHT22  sensor  for  temperature  and  humidity readings in the box with the peltier thermoelectric TEC1-12706 as a cold temperature generator that will lower room temperature. Additional HC-SR04 ultrasonic sensor for object detection in the box and DS18B20 sensor for temperature reading in the peltier. Monitoring system using 16x2 LCD with temperature and humidity screen display. The system works from controlling the Arduino Uno, reading the temperature of DHT22 as a switching peltier and water pump. Then the DS18B20 temperature reading is used as a switching fan cooler and the DHT22 humidity reading is used as a switching fan exhaust.
