RANCANG BANGUN SETRIKA LISTRIK DENGAN SISTEM KONTROL SENTUH DAN PENGAMAN OTOMATIS BERBASIS ARDUINO NANO

Abstract

Along with the rapid development of technology and the increasing demand for comfort in daily life, household appliances such as electric irons require innovation in temperature control and automatic safety systems. Conventional electric irons still use manual rotary controls and mechanical thermostats, which have several drawbacks, including the absence of real-time temperature feedback and changes in the thermostat curvature point that cause the temperature to be inconsistent with fabric requirements.This research aims to design and develop an electric iron with a touch control system and an automatic safety mechanism based on the Arduino Nano to improve temperature stability and user safety. The system utilizes a PT1000 temperature sensor to detect the heating plate temperature, a TTP223 touch sensor for fabric type selection, and an Arduino Nano as the main controller. Heating power regulation is carried out using an optocoupler and TRIAC circuit, while temperature and mode information are displayed on an OLED screen. The results of this design show that the electric iron is able to maintain the temperature close to the setpoint with a relatively small error, and the automatic safety system functions properly when the iron is not in use.
