There will be unexpected crowds in certain places, such as shopping malls, gaming venues, or other spots with seasonal traffic. We observe that many people arrive quickly without warning, which makes it difficult to manage resources, creates imbalances because of crowding, and manages parking and traffic, among other issues. IR sensors are the greatest option for counting people because they are affordable and simplify and improve the system. Controlling the entry and exit gates with servo motors is all that is required to keep an eye on the throng. The system also includes a buzzer-based exit gate control method for schools and other locations that require exit gate control. With advance knowledge about the crowd in a given region, the system keeps an eye on and manages the crowd, providing necessary individuals with information or a warning. In addition to controlling and monitoring the crowd without allowing for human interaction, the system also uses a bell to ensure that people leave the designated area. The system can be expanded to meet needs like managing student arrivals and departures from schools, keeping crowds within a set number of people in busy situations, parking lots, etc.
