During the COVID-19 pandemic, all activities that involve large numbers of people arereduced to reduce the potential spread of the COVID-19 virus. So the number of people in aroom is important in the current pandemic era. To assist in determining the capacity of thenumber of people in a room, a system can be created to count the number of people in theroom so that the room is always in accordance with the predetermined capacity. Therefore,this study aims to create a system for counting the number of people in an IoT-based roomusing ESP32 as a control center, proximity sensor E18-D80NK to detect the presence ofobjects, 4x4 matrix keypad to enter the specified number of data, DC-DC buck converterstep down as a voltage reducer so that the ESP32 and selonoid doorlock can function, LCDI2C and by using Blynk.
