Datasheet http://www.micropik.com/PDF/HCSR04.pdf Notes The HC-SR04 is one of the lowest cost Sonar-based distance sensor options available (as low as $3 US). There seem to be several hardware versions and/or clones that work the same as far the functions of the two pins (trigger ...
I’ve serched the HC-SR04 datasheet and it says indeed the output is 5V, but the oscilloscope reads 3.3V. Why? Thank you! Reply Juergen Dietrich July 23, 2021 at 7:50 pm Many thanks Sara I trusted you and I copied your circuit as shown in your website (even without series resist...

To measure the distance, 1, send a high voltage from pin PC5 to trigger, Luke used 5us, but the HC-SR04 datasheet says at least 10us. Confusion 1. 2, we set the timer basic unit as 74 cpu cycles, that is 5us. 3, once the PC5 is set to high for that 5us (or 10us), ...
