Count Objects Using Arduino and Ultrasonic Sensor on a Production Conveyor : Intro: This instructable explains how to use an ULTRASONIC SENSOR with Arduino to count/ log different packages on a conveyor.

Mar 7, 2020 · Ultrasonic Sensor as a counter with Arduino. Hi in this tutorial we will see how to use ultrasonic sensor as a counter and output will be shown on LCD display. It will count number of times object passes in front of sensor. Provide separate ground for ultrasonic sensor. And connect VCC pin near to 5V pin.

This instructable explains how to use a potentiometer and an ultrasonic sensor with arduino to count/measure/log different objects on a conveyor. There will also be some LED's which will flash with different speed and a different number of times.

May 2, 2024 · Learn how to use the ultrasonic sensor (HC-SR04) with Arduino. This tutorial will teach you what it is, how to assemble the sensor on Arduino, and, at the end, you'll implement it into an alarm system project.

May 30, 2024 · In this project, we will be using the HC-SR04 ultrasonic sensor module. This sensor can detect objects from 2 cm to 400 cm, or roughly, 1 inch to 13 feet. The sensing angle is 15 degrees or less. Its operating voltage is 5 volts. The pins of the HC-SR04 are VCC, TRIG, ECHO, and GND.

Jul 10, 2013 · There is a task: physical count of people entering through the door. Using Arduino UNO + HC-SR04 + Lcd keypad shield from DFrobot. sketch: Serial.begin(9600); lcd.begin(5, 1); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(LEDPin, OUTPUT); // Use LED indicator (if required)

The ultrasonic transceivers, that are the #transmitters and #receivers, use the concept of converting electrical energy into ultrasonic sound. The ultrasonic sensor emits sound waves at a frequency above human hearing and calculates the distance of any object or obstacle in its path.

Sep 22, 2020 · Use a universal 4-pin grove cable to connect the ultrasonic sensor in pin D7 to the arduino board. Using the USB A/B cable to connect the arduino development board to the computer. The distance between the sensor and the ground is 128 mm.

This project is a simple people counting system that uses an ultrasonic sensor, an Arduino board, and an LCD display to count the number of people passing through a specific location. The system is designed to be easy to set up and use, making it a great solution for a variety of applications such as retail stores, libraries, museums, and more.
