To address this need, a touchless parking portal was designed using a microcontroller-based and internet of things (IoT) -based system, with the Arduino UNO microcontroller device serving as the core component. The system employs an ultrasonic sensor HC-SR04 and passive infrared (PIR) to detect vehicles as they arrive at the portal area, in addition to requiring an ESP32-CAM camera, servo motor, light-emitting diode (LED), I2C 16x2 liquid crystal display (LCD), push button, universal serial bus (USB) to transistor-transistor logic (TTL) converter, power supply, and portal bar. The system builder software was developed using Arduino integrated development environment (IDE), Android, and Blynk. The authors conducted thorough testing and analysis of the system, concluding that its overall performance reaches 100%. Nevertheless, despite the extensive experimentation conducted, there remains a possibility that certain factors could still affect the results. Therefore, caution is advised when interpreting the outcomes of this experiment.

INTRODUCTION The spread of the COVID-19 virus in the current era of globalization is increasingly widespread and continues to increase every day by hitting various countries around the world for more than a year [1]. COVID-19 is a respiratory disease caused by a virus (SARSCoV-2) that can cause respiratory infections, coughs, severe pneumonia, and even death. In breaking or reducing the spread of the virus, the government has established health protocols to minimize touching or direct contact between humans and objects around them in daily life. One of them is the use of a touchless automatic parking portal. That's why we designed a microcontroller and internet of things (IoT)-based touchless parking portal design. The significance of the touchless parking portal design lies in its ability to address the pressing need to minimize direct contact between people and objects in public areas, such as parking lots [2]. This project is crucial in the fight against the spread of COVID-19, especially in highly frequented locations. The
