Pemanfaatan Sensor MLX90614 sebagai Sensor Pembuka Pintu dan Sterilisasi dengan Sinar UV Berbasis Mikrokontroler ATMEGA328

Abstract

In this study, the energy needed is obtained from solar energy which is then converted into electrical energy with the help of solar cells. Batteries and solar cells are two devices that can convert sunlight into direct electrical energy. The energy storage power of the battery can be converted into AC or DC current. Making a miniature automatic door using a temperature sensor is an innovation where the door has a non-contact temperature sensor MLX90164 and UV light sterilization using an ATMega 328 microcontroller. There are 2 sensors, namely the MLX90614 temperature sensor, and a proximity sensor. These two sensors will make readings of existing objects. After that, all types of input that have been received from the sensor will be forwarded to the Atmega328 and then it will be processed according to the program that has been made. After that the output will appear on the LCD according to the object. Then, the results from the LCD are forwarded by the Atmega 328 to the servo motor which functions to open the door after the object's body temperature is normal. If the body temperature is <38°C, the door will open and the data will be displayed on the LCD. Please enter and the UV light will light up for 3 seconds. Then the use of the buzzer as an alarm will give a "Beep" sound as a marker. If the body temperature is >38°C, the buzzer will sound, and the door will not open.
