Distance Measurement:
This Project uses Ultrasound to measure distance. Measured distance is
displayed on LCD. You can use this digital output data in making many
interesting projects such as accident proof vehicle or Robots, object
identifier, Sonar
.
The speed of sound travels depends on the medium which it passes
through. In the air speed is approximately 345 m/s, in water 1500 m/s
and in a bar of steel 5000 m/s. So we can use ultrasound and by
calculating Time we can find distance. This type of range finding is
also called Sonar. Sonar works similarly to Radar. To measure the
distance of a sound ravelled, it needs to be reflected.
distance = time X velocity.
this project you will need Transducer and Sensors for Ultrasound
Transmission and Detection. One such Transceivers is HC-SR04 Module.
These devices typically transmit a short burst of ultrasonic sound
toward a target and detect sound back to the sensor. Beside this you
will need Arduino Board and 16×2 LCD Display.
