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 ...

In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to the receiver. You can ...

The Arduino Uno R3 Compatible Board is a microcontroller board that is based on the ATmega328. Arduino Uno has 14 digital input or output pins(where 6 can be used as ...

Abstract: 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 ...

Abstract: 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 ...

Why BMP280, you ask? Because this sensor costs low and it only provides both temperature and barometer readings, and as pressure changes with altitude, we can also use it as an altimeter with ±1 meter ...
