Starting from the beginning of March 2019 and even until the end of 2020, the Indonesian people are experienced prolonged suffering due to the emergence of a new type of infectious disease called Corona Virus 2019. Social Distancing is a program that aims to prevent the transmission of the COVID-19 disease as early as possible. In this research, the method used is the observation technique and literature study for the implementation of the HC-SR04 sensor as one of the distance sensors used for distance reminders implemented in public spaces using IoT as a monitoring system. The results obtained are the reading accuracy of the HC-SR04 sensor is quite accurate to 100% accuracy and when the HC-SR04 sensor detects less than 8cm (1meter real distance) then the DF Player will sound, the LCD will display a display “Jaga Jarak Anda! ", And there will be a notification"Peringatan: Kondisikan Jarak" on a smartphone that has the Blynk application installed.
