Overcrowding of the venue leads to the attendees' health and safety risks, which can often lead to injury or harm. The goal of this paper is to design and implement a circuit to avoid overcrowding of venues by counting people and controlling entrance door. Two main circuit designs accomplish this objective; one for counting, and the other for regulating. The counting circuit is based on the use of infrared rays and the FC-51 proximity sensor to detect motion. The control circuit is based on the PIC16F887 microcontroller which is assisted as peripheral by servo motors and buttons. When the venue is complete based on the allocated maximum number of persons permitted in accordance with the proximity sensor, a signal is sent to the servo motor attached to the entrance door for a 90o displacement to close the door. This closing of the entrance limits further inflow into the venue; thus overcrowding of the venue is avoided. The results obtained showed that the expected output voltages for the design of the power supply unit for each subunit were within a tolerance range of ±0,6V. The systems for input, control and display operated also properly. As such, the proposed application may be deployed in a desired place to prevent overcrowding.
