The following picture shows the HC-SR04 ultrasonic sensor. The next picture shows the other side of the sensor. Features Here’s a list of some of the HC-SR04 ultrasonic sensor features and specs—for more information, you should consult the sensor’s datasheet: Power Supply :+5V DC Quiesc...
The main thing I like about the NewPing library is that it has a built-in median filter. This filter can greatly improve the accuracy of your HC-SR04 readings. Theping_median()function takes many duration measurements in a row, throws away the out of range readings and then averages the ...
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 resi...
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 ...
Then the HC-SR04 automatically sends Eight 40 kHz sound wave and wait for rising edge output at Echo pin. When the rising edge capture occurs at Echo pin, start the Timer and wait for falling edge on Echo pin. As soon as the falling edge is captured at the Echo pin, read the count...
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), ...
