Arduino Uno Based Automatic Hand Sanitizer, Servo, and Infrared Sensor

Abstract

Hand Sanitizer is a hand sanitizer that has antibacterial ability to inhibit and kill bacteria. There are two types of Hand Sanitizer, namely Hand Sanitizer gel and Hand Sanitizer spray. Currently, countries in Asia and Europe, including Indonesia, are being hit by disasters, one of which is the Corona virus. Based on this problem, an Arduino Uno-Based Automatic Hand Sanitizer was made using a Sensor which aims to reduce the spread of the virus by taking precautions such as cleaning hands, minimizing direct contact with other people, and reducing touching objects in public places that are often touched by many people. This tool uses an infrared sensor, where this sensor detects objects that are blocking it and the servo motor will rotate to press the bottle cap of the Hand Sanitizer. To make an Arduino Uno-Based Automatic Hand Sanitizer Using the FC-51 Infrared Sensor, this is done in several stages, namely making a program with Arduino.IDE to provide instructions that will be programmed to make it easier for users.  Keywords :Arduino Uno, Infrared Sensor, Servo Motor
