The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do.
Ultrasonic sensor arduino project pdf.
Obstacle distance is measured using ultrasonic sensor and arduino.
The ultrasonic pulses collide an object and leaves in the other direction the echo terminals receives the ultrasound pulses and the sensor calculates the distance based on the time of the pulses.
Distance measurement of an object in the path of a person equipment or a vehicle stationary or moving is used in a large number of applications such as robotic movement control vehicle control blind man 39 s walking stick medical applications.
Ultrasonic rangefinder with processing.
The data is processed using processing and the distance is marked.
Concept behind smart dustbin using arduino.
Check the serial monitor readings.
Connect the positive terminal with pin 8 of arduino and negative terminal to gnd.
Connect the vcc and gnd.
The main concept behind the smart dustbin using arduino project is object detection.
This project uses an ultrasonic distance sensor to create a pocket of wave interference where a small object can be levitated.
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.
The objective of this project is to notify the user the amount of water that is present in the overhead water tank.
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.
This project lights a set of led s depending upon the distance of the obstacle with respect to the ultrasonic sensor.
Connect the trigger pin to pin 12 and echo pin to pin 13 of arduino.
Arduino is a small microcontroller board with a usb plug to connect to the computer.
Water level indicator using arduino.
The setup is now ready.
A sensor is a device that converts one type of energy to another.
Wireless water level indicator using ultrasonic sensor arduino is an amazing and very useful project.
