PCR (Portable Covid Reminder) is a tool to anticipate the transmission of COVID 19 with an ultrasonic sensor and a reminder speaker that can detect people within 1-3 meters. PCR can be placed at the entrance to a room or car. PCR is made portable because of its minimalist shape so that it can be carried or installed as desired. PCR only needs a current source from a rechargeable battery so it will be more efficient. Innovator: Dr. Bambang Sudarsono, M.Pd., Dr. Fatwa Tentama, M.Psi., Fanani Arief Ghozali. M.Pd.,
