Distance Measurement Using Ultrasonic Sensor And Arduino Code

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.

Distance measurement using ultrasonic sensor and arduino code.

The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. Distance measurement using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely. Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor. Ultrasonic sensors not only offer distance measuring utility without any physical contact but enable us to measure with no noise and light unlike laser based distance measuring instruments.

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. So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor. The ultrasonic sensor is consists of transmitter and receiver modules. It is simply based on using the echo.

What is ultrasonic sensor. The ultrasonic sensor is used to measure the distance. In circuit connections ultrasonic sensor module s trigger and echo pins are directly connected to pin 18 a4 and 19 a5 of arduino. It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.
