12/31/2023 0 Comments Ultrasonic sensor arduino 4 pinWhen any object or obstacle comes in front of the sensor then the sensor measure distance between the object or obstacle and it. Using this project we can easily understand how the ultrasonic sensor works. In this project, we are going to make a distance measuring device using the ultrasonic sensor and Arduino, which can measure distance in the range of 2 cm to 400 cm.

Measuring angle covered: 20 & distance 400 ) OUTPUT.Practical Measuring Distance: 2 cm to 80 cm.Theoretical Measuring Distance: 2 cm to 400 cm.This pin is connected to the Ground of the system. This pin goes high for a period of time which will be equal to the time taken for the US wave to return back to the sensor. This pin has to be kept high for 10 us to initialize measurement by sending US waves. The Vcc pin powers the sensor, typically with +5V ULTRASONIC SENSOR PIN CONFIGURATION Pin Number The circuitry inbuilt on the module will calculate the time taken for the ultrasonic wave to come back where the echo pin turned high for that same amount of time, this way we can also know the time taken. Since we are using the Ultrasonic wave we know the universal speed of US wave at room conditions which is 343 m/s. Now, to calculate the distance using the above formula, we should know the Speed and time. The Ultrasonic transmitter transmits ultrasonic wave pulse, this wave travels in the air and when it gets objected by any material or obstacle it gets reflected back toward the sensor or in other words when an obstacle detected waves reflects back towards the sensor, this reflected wave is observed by the Ultrasonic receiver see picture below The sensor works with the simple formula that is Distance = Speed × Time Generally Ultrasonic sensor is used in applications where measuring distance and/or sensing objects is required. In simple terms, we can say Trig is a transmitter and the Echo is a receiver. We know the velocity of sound is 343 m/s & if we can get time taken by the wave to travel, then, we can easily calculate distance between the sensor and the obstacle. The ultrasonic sensor is a sensor which emits ultrasonic sound waves from its transmitter and this sound wave returns back to the receiver of the sensor after reflecting from an obstacle or surface and calculates the total time taken by the wave to get return. In this tutorial, we will see how to interface ultrasonic sensor with arduino and how to get its output on the serial monitor.
