Distance Measurement Using Ultrasonic Sensor And Arduino Ppt

Ultrasonic sensors are a great fit for many applications like distance measurement and level sensing.

Distance measurement using ultrasonic sensor and arduino ppt.

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. The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. 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. So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor. 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 using arduino ultrasonic sensor is a very easy project to measure shorter distance precisely.

It acts as a sonar. 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. The ultrasonic sensor is consists of transmitter and receiver modules. Arduino s pins can generate a 10 microsecond pulse and measure the pulse duration.

Find more about the working of distance measurement project in this tutorial. Ultrasonic sensor maximum range. This article covers the advantages and limitations of. An ultrasonic distance measurement is a non contact distance ranging technique.

How to measure distance using ultrasonic sensor hc sr04 and arduino. And then perform calculations and displayed result on 16x2 lcd by using appropriate functions. Then the time delay between transmission of sound. Therefore we can get the distance from the ultrasonic sensor by using two arduino s pins.

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. Check this project using oled display. Sensors with a maximum range of 254 inches. In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04.

It works by sending out a sound wave at ultrasonic frequency and waits for it to bounce back from the object. Another pin is connected to echo pin measure pulse from the. An ultrasonic sensor is a device that measures distance to an object using sound waves. Sensors by maximum range.

Arduino ultrasonic sensor. Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino. Interfacing ultrasonic sensor with arduino. In code we read time by using pulsein pin.

Distance measurement using ultrasonic sensor. One pin is connected to trig pin to generate 10µs pulse to trig pin of the sensor.
