Distance Measurement Using Ultrasonic Sensor And Arduino Ppt

An ultrasonic sensor is a device that measures distance to an object using sound waves.

Distance measurement using ultrasonic sensor and arduino ppt.

It is simply based on using the echo. Here we are using a high precision hcsr 04 ultrasonic sensor module for the arduino based distance measurement. Another pin is connected to echo pin measure pulse from the. Interfacing ultrasonic sensor with arduino.

Arduino ultrasonic sensor code for distance measurement. An ultrasonic distance measurement is a non contact distance ranging technique. Our sensors range from 20cm to our only 16 5m sensor our cargo detection sensor. Distance measurement using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely.

The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. Arduino s pins can generate a 10 microsecond pulse and measure the pulse duration. The ultrasonic sensor is used to measure the distance. Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino.

One pin is connected to trig pin to generate 10µs pulse to trig pin of the sensor. It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package from 2 cm to 400 cm or 1 to 13 feet. So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor. In code we read time by using pulsein pin.

Then the time delay between transmission of sound. Therefore we can get the distance from the ultrasonic sensor by using two arduino s pins. It works by sending out a sound wave at ultrasonic frequency and waits for it to bounce back from the object. It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.

Distance measurement of an object in the path of a person equipment or a vehicle stationary or moving is used in a large number of applications such as robotic movement control vehicle control blind man 39 s walking stick medical applications. And then perform calculations and displayed result on 16x2 lcd by using appropriate functions. That is calculating the distance by analysing the time required for the propagation of sound waves. Sensors by maximum range.

Find more about the working of distance measurement project in this tutorial. How to measure distance using ultrasonic sensor hc sr04 and arduino. Before getting started you must know about ultrasonic sensor hc sr 04 which is a low cost sensor. Ultrasonic sensors are a great fit for many applications like distance measurement and level sensing.
