Is the low cost ultrasonic in your catalog can detect any piece of paper ? How far its sensitivity? My capstone project is about to built the smart assignment box and need any suggestion for suitable sensor that can detect non metallic object like papers.
What's the end goal of the project? Differentiate paper from stone, detect the existence of paper in an open air, determine the distance between paper and sensor?
