So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor.
Distance measurement using ultrasonic sensor and arduino code.
The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance.
The ultrasonic sensor is consists of transmitter and receiver modules.
What is ultrasonic sensor.
That is calculating the distance by analysing the time required for the propagation of sound waves.
Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor.
It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.
How to measure distance using ultrasonic sensor hc sr04 and arduino.
The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do.
It acts as a sonar.
Ultra sonic sensor is a device which is capable of transmitting and receiving ultra sonic sound waves out into the air and calculates the distance from the sensor to the obstacle by making use of the time required for the sound wave to reach back the sensor.
In circuit connections ultrasonic sensor module s trigger and echo pins are directly connected to pin 18 a4 and 19 a5 of arduino.
The ultrasonic sensor is used to measure the distance.
An ultrasonic distance measurement is a non contact distance ranging technique.
Thakur the hc sr04 ultrasonic sensor is a very affordable proximity distance sensor that has been used mainly for object avoidance in various robotics projects.
