Utilization of Solar Cells as Energy Sources for Heating and Fan (Ex-house) in White Copra Dryers with Arduino Uno as Temperature Control

摘要

One of the electronic technology that has been developed in this research is to use Solar Cell as a source of heating energy and a fan to control the temperature of the drying chamber. In this study developed using the Arduino Uno Microcontroller as the center of the data controller, adjust the display on the LCD, translate the analog from the LM35 temperature sensor, and the LDR sensor to control the room temperature so that the temperature remains stable. The temperature of the room where the temperature is controlled from 6 oC-S$heta$ oC as a temperature temperature condition to produce white copra with good quality, then the input received from the temperature sensor will be processed by the Arduino Uno microcontroller then activates the heater at night and activates the fan during the day to suck hot air if the oven temperature is more than 8$heta$ oC, in addition to hardware in the form of control circuits, also use C language with the Arduino IDE Software as the software.
