Rancang Bangun Alat Pengaduk Susu Menggunakan Sensor Ultrasonik Dilengkapi Sistem Sterilisasi Berbasis Arduino

Abstract

Milk is a food that has been known since ancient times and is a special food ingredient for humans because of its deliciousness and ideal composition and contains all the substances needed by the body. From a nutritional point of view, milk is an almost perfect food and is a natural food for newborn mammals, where milk is the only source of food immediately after birth. In technology, there have been many discoveries that are very useful for humans, one of which is the invention of tools that use sensors, where the sensor is a kind of transducer (energy converter) that is used to convert mechanical, magnetic, heat, light and chemical variations into voltage and electric current. In this study, it was built with electronic components and sensors on the basis of an Arduino microcontroller and the program to be designed. This design also uses an ultrasonic sensor and is equipped with sterilization, which when the milk stirrer passes through the ultrasonic sensor, the ultrasonic sensor reads the measurement then the milk stirrer is on and the UVC lamp is on. After 1 minute, the LCD will display “Steril” which means that the milk stirrer is sterile.
