PiicoDev Ultrasonic Rangefinder | Getting Started Guide for Raspberry Pi
The full guide: https://core-electronics.com.au/guide...
Let's get started measuring distance with the PiicoDev® Ultrasonic Rangefinder. We'll connect this sensor to a Raspberry Pi and begin measuring distance - then remix the code to change how it works!
Similar to how bats echo-locate and how submarines use sonar, the PiicoDev Ultrasonic Rangefinder uses sound waves to measure the distance to an object. It sends out a high-pitched sound wave, which bounces off of the object and comes back to the sensor. The time it takes for the sound wave to go out and come back is used to calculate the distance to the object. Think of it like shouting and listening for an echo! By knowing how long it takes for the echo to come back, we can calculate how far away the object is.
