General description
The UTR2 is an hybrid circuit that allows to
realize an ultrasonic detector addingfew
external components.
Detection is based on amplitude variation of received
ultrasonic signal (40KHz) due to the movement of an
object.
It shows stable electric characteristics thanks to
the
"Thick film hybrid" tecnhology.
