Ultrasonic Sensor Arduino Project Report

The basic principle behind the working of ultrasonic sensor is to note down the time taken by sensor to transmit ultrasonic beams and receiving the ultrasonic beams after hitting the surface.

Ultrasonic sensor arduino project report.

Vcc is the power supply for hc sr04 ultrasonic distance sensor which we connect the 5v pin on the arduino. Arduino ultrasonic sensor code for distance measurement. Connect the vcc and gnd. Check the serial monitor readings.

Transmitter circuit transmitter circuit is shown in the figure below fig1 in this circuit an ultrasonic sensor is connected to pin d9 and d10 pin of arduino. Gnd should be connected to the ground of arduino. Echo pin produces a pulse when the reflected signal is received. Find more about the working of distance measurement project in this tutorial.

Connect the positive terminal with pin 8 of arduino and negative terminal to gnd. Trig trigger pin is used to trigger the ultrasonic sound pulses. The length of the pulse is proportional to the time it took for the transmitted signal to be detected. First of all we need to trigger the ultrasonic sensor module to transmit signal by using arduino and then wait for receive echo.

Connect the trigger pin to pin 12 and echo pin to pin 13 of arduino. In this project i have designed a simple system called smart dustbin using arduino ultrasonic sensor and servo motor where the lid of the dustbin will automatically open itself upon detection of human hand. In this project two circuits are used. Find these and other hardware projects on arduino project hub.

In code we read time by using pulsein pin. Now load the code in arduino ide and then upload it to arduino. Of course i will be using different hardware like arduino uno hc sr04 ultrasonic sensor and a servo motor but the main aspect is the visual representation in the processing application. Control pin rs rw and e are directly connected to arduino pin respectively 2 gnd and 3.

The main concept behind the smart dustbin using arduino project is object detection. A 16x2 lcd is connected with arduino in 4 bit mode. Explore 68 projects tagged with ultrasonic. And then perform calculations and displayed result on 16x2 lcd by using appropriate functions.

Then further the distance is calculated using the formula. Concept behind smart dustbin using arduino. The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. The setup is now ready.

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. And data pin d4 d7 is connected to 4 5 6 and 7 of arduino. Arduino water level indicator circuit. To use this sensor.
