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.
Ultrasonic sensor arduino project report. Check the serial monitor readings. Gnd should be connected to the ground of arduino. Arduino water level indicator circuit. And data pin d4 d7 is connected to 4 5 6 and 7 of arduino.
Explore 68 projects tagged with ultrasonic. Then further the distance is calculated using the formula. 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. A 16x2 lcd is connected with arduino in 4 bit mode.
Find these and other hardware projects on arduino project hub. To use this sensor. Find more about the working of distance measurement project in this tutorial. In this project two circuits are used.
Echo pin produces a pulse when the reflected signal is received. Arduino ultrasonic sensor code for distance measurement. Distance measurement using ultrasonic sensor. 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.
Connect the trigger pin to pin 12 and echo pin to pin 13 of arduino. First of all we need to trigger the ultrasonic sensor module to transmit signal by using arduino and then wait for receive echo. The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do. Now load the code in arduino ide and then upload it to arduino.
Trig trigger pin is used to trigger the ultrasonic sound pulses. 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 code we read time by using pulsein pin. Connect the positive terminal with pin 8 of arduino and negative terminal to gnd.
In this project the widely available hc sr04 ultrasonic sensor is used. 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. And then perform calculations and displayed result on 16x2 lcd by using appropriate functions. The setup is now ready.
Control pin rs rw and e are directly connected to arduino pin respectively 2 gnd and 3. Connect the vcc and gnd. 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. The main concept behind the smart dustbin using arduino project is object detection.
