It works by sending sound waves from the transmitter, which then bounce off of an object Allows an Arduino board to use HCSR04 module. So, the known parameters are time and speed (constant). It has additional information and examples for the sensor, including specifications, pinouts, wiring diagrams, codes and more. Have your Arduino read the ultrasound sensor. How to interface I2C LCD display with Arduino ? WebConnect Arduino to PC via USB cable. Will it burn or get hot? According to the amount of time the Echo pin was HIGH, we can determine the distance the sound wave traveled, thus the distance from the sensor to the object. We know that the speed of sound in air is nearly 344 m/s. arduino ultrasonic sensor calibration,16. If we want the get the distance result in cm, we can convert the speed of sound value from 340m/s to 34cm/ms. Copyright 2018 - 2023 ArduinoGetStarted.com.
