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 ...

This is just a simple program I wrote for an Arduino Mega 2560 board with a generic ultra-sonic sensor and a 16x2 LCD display board. The main point for me is just to learn how to write C++ and gain ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

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 ...

Parking sensors have become a must-have these days given the crowded cities we live in, but instead of paying hundreds of dollars to get them installed in your car, why not build your own at home?
