Good item

Easily plugged with a Arduino Uno using the Newping library. I am a a newbie with Arduino and I noticed that sometimes I received a distance à 0 even if there's an object in front of the sensor. I don't know why. I have to investigate this issue. Maybe there's something wrong in my code.
