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 ultrasonic sensor and arduino uno code.
Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino.
Distance measurement using ultrasonic sensor and arduino uno code.
Open a new sketch file by clicking new.
The module sends 40 khz signals automatically and then detects whether the pulse is received or not through echo.
Follow the circuit diagram and make the connections as shown in the image given below.
Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.
1 arduino uno r3.
Download the i2c lcd library.
So let s learn about distance measurement using arduino hc sr04 ultrasonic sensor.
Hc sr04 ultra sonic sensor.
Coding in the arduino language will control your circuit.
Arduino ultrasonic sensor code for distance measurement.
The high level signal is sent to 10 microseconds using trigger.
Open the arduino ide software on your computer.
1 ultrasonic sensor hc sr04 procedure.
Distance measurement using ultrasonic sensor.
And then perform calculations and displayed result on 16x2 lcd by using appropriate functions.
Working of ultrasonic sensor.
In code we read time by using pulsein pin.
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.
