1. The **HC-SR04** emits ultrasonic waves and measures the time it takes for them to bounce back. 2. The **Arduino Nano** calculates the distance using the speed of sound. 3. If an object is detected ...

Inside the light is an Arduino Nano, which reads from the ultrasonic sensor mounted underneath the enclosure and lights up the appropriate LED depending on the car’s distance.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...

Arduino Uno – Powered Parking Guidance System with Ultrasonic Sensors" is a smart and innovative solution for simplifying the parking process in crowded urban environments. This paper leverages the ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

The treat in question is detected by an SR-04 ultrasonic distance sensor connected to an Arduino Nano. All in all this was a highly successful build as far as neighborhood entertainment value goes.
