HCSR04 is an Ultrasonic ranging module which consists of a transmitter,receiver and control circuit. It has four pins for VCC, GND, Trigger and Echo.You can easily interface it with micrcontrollers and Arduino boards.
The basic principle of work is:
(1) Using IO trigger for at least 10us high level signal,
(2) The Module automatically sends eight 40 kHz and detect whether there is a
pulse signal back.
(3) IF the signal back, through high level , time of high output IO duration is
the time from sending ultrasonic to returning.
Test distance = (high level time×velocity of sound (340M/S) / 2

Is it going to fry Arduino Due's pin? Probably foolish to ask, cause it is 5v and Due pins are 3•3v(maybe?), But asking.

What is your order ID?
By techshop on 25 Mar 2018
My order ID was #109828. It was bought long time ago and never used before 24th March, 2018. But another sensor which was giving exact distance bought 8 years ago and used once or twice.
