This pin will remain in the high state for the duration of time that will be exactly equal to the time taken by the ultrasonic wave to travel from the transmitter and back to the receiver of the sensor. When the ultrasonic wave will be received by the receiver after reflecting the sensor, it will put the eco pin to a high state. this wave will travel in the air and as soon as it strikes an object in its way, it will strike back and received by the receiver built in the sensor. An 8 sonic burst of ultrasonic waves is sent from the transmitter as soon as this task is done. This task is done by triggering the trig pin for 10us. The process is initiated by sending an ultrasonic wave from the sensor. This sensor has two pins, trigger pin, and eco pin that are both used to measure the distance between two particular points. You can understand the main working of this sensor by the following diagram. Step 3: Working of The HCR-05Īs we now know the main abstract of our project, let us move ahead and go through a brief study of the working of HCR-05.
Two point measure software#
I have included software simulations here so that it may be convenient for beginners to design the circuit and make appropriate connections on the hardware.

How to Use Arduino and Ultrasonic Sensor To Measure Distance?Īs we know the summary behind the project, let us move ahead and gather further information to start the project. All the challenges that were faced while carrying out this project are discussed below. To implement it on a large scale, some modifications are surely needed. The Technique used here is just useful on small scale systems where a small distance is to be found. The Technique we are using here is called Triangulation. By doing so, we will be able to measure the distance between them just by locating the position of the transmitter by using many ultrasonic receivers. One sensor will be made a receiver and the other will be made a transmitter. These two modules will be placed at two different points between which the distance is to be measured. We are going to use two separate ultrasonic sensors that will be integrated with two separate Arduino. But in this article, we are going to adopt a different approach.
Two point measure code#
It is very easy to write a code on the Arduino board and integrate an ultrasonic sensor to carry out this task. In Electronics, most of the time Ultrasonic Sensors are used to measure the distance from one particular point to another.
