The Number of Visitor of the Class Pandemic Time Corona Virus Disease Limit During 2019 Based on Internet of Thing

Abstract

Number of visitors to engineering laboratory restrictions were carried out, because it could lead to crowds of students, resulting in the transmission of the SARS-CoV-2 virus that causes covid-19. The Telecommunications Engineering Laboratory is one of the facilities at the Sriwijaya State Polytechnic, which is used by all students to understand practically the telecommunication field. The design and manufacture of this tool aims to create a laboratory environment that is in accordance with health protocols in order to prevent transmission of CoronaVirus Disease 2019 (Covid-19). The system for limiting the number of visitors to the telecommunications engineering laboratory uses RFID (Radio Frequency Identification), Magnetic Sensors, Webcams and Touchless Buttons as input functions. This system uses Arduino Mega 2560 and Raspberry Pi 3 as the system's main controller processes. Component output using Magnetic door lock, LCD 16x2, LED, Relay, and Warning Light LED. Magnetic door lock functions as a door lock, 16x2 lcd as a monitoring system work process, relay as a switch or switch to disconnect and connect electric current, led and warning light led as an indicator.
