Automatic Face Mask
The Project
The principle that this automatic mask works on is that an ultrasonic sends sound waves which we cannot hear to identify the position of a person nearby. If the sound waves are received by the receiver of the sensor before a certain time amount (about 30 milliseconds) it will pass the data to Arduino UNO. The Arduino UNO will then transmit a signal to servo motors which will pull the mask up to cover the person’s face completely.
