CONCEPT
The ultrasonic sensor detects the distance of an object and gives a reading of the same on the LCD screen. If the distance is above 10 cm, the Green Led turns ON and if the distance goes below 10 cm the Red Led turns ON and the buzzer produces a noise alerting the user of the object being too close. The safety distance buzzer can be used in places like parkings , automatic openings, organising fragile objects in a commercial space or even like a personal space protector.
