Automatic Door Bell Using Arduino UNO and Buzzer

The Project

I created an Automatic Door Bell using an Arduino Uno, ultrasonic sensor, and a buzzer. When someone comes near the door, the ultrasonic sensor detects their presence and automatically triggers the buzzer to ring. Inspiration: Inspired by the need for touchless systems and smart automation, especially during the pandemic, I wanted to create a contact-free doorbell to enhance hygiene and convenience. What was difficult? The challenge was adjusting the sensor's detection range accurately to avoid false rings from distant movements or pets. Applications: Smart homes and apartments Contactless systems in public places Automation for elderly or disabled individuals School or office entrances for visitor alert systems
