This tutorial demonstrates the correct way to solder wires to a piezoelectric sensor. First, the stripped wires are tinned (coated with a thin layer of solder). Then the piezoelectric sensor, held in a small adjustable clip, is heated briefly, and two drops of solder placed where the wires are to be attached. Finally, the tinned ends of the wires are placed in contact with the soldered areas of the piezoelectric sensor, and the solder heated to fix the wires in place.
