People Counting Automatic Barrier (CrowdStopper): An IoT Prototype Design

The emergence and occurrence of COVID-19 pandemic has affected the lives of many people around the world, implementing different protocols to further prevent the spread of this deadly virus. Overcrowding is one of the common reasons for the spread of any virus or diseases. The researchers aim to create a system that monitors crowd density inside a building or infrastructure to avoid overcrowding. This system primarily utilizes ultrasonic sensors to detect entry and exit of an individual. The feedback will be sent to the user and the data will be used to effectively monitor the number of people inside the building. © 2022 ACM.
