Hello,
I want to design a handy object detector of USB drive size. I want to detect object at 1 ft distance. There is also requirement to detect object if it remains for 1 minute before the detector. After one min. detector give buzzer to indicate the presence of the object.
I myself feel Ultrasonic sensor is ok
But what to with buzzer and batter size.
Any help to make it in compact size
