All the versions of ultrasonic radars I have found for arduino devices (Arduino – Radar/Ultrasonic Detector, Arduino Ultrasonic Radar Project) are very nice radars but all of them are “blind”. I mean, the radar detects something but what is it detecting? So I propose myself to develope a system able to detects objets and identyfy them.

This instructable describes how to create a non-contact range-finder using an Arduino and an HC-SR04 ultrasonic module to measure distances in the range 2cm – 400cm. The accuracy is typically +/- 3mm depending on distance, air temperature, and humidity. Step 1: Parts List Very few parts are required: 1 only HC-SR04 ultrasonic module or similar

This simple Arduino project can be placed in the doorway of a shop or other venue to count the number of people inside. Limiting the number of people inside a space can help to maintain social distancing. A demonstration of this project can be found here. There is no soldering required in this project, since all

This project demonstrates the functioning of an “Ultrasonic Mono-pulse Tracker” built using two Grove ultrasonic sensors. Two sensors facing forward at a small angle from each other are placed on a servo pedestal capable of rotating +/- 60 degrees based on commands from an Arduino UNO board. The “Amplitude Comparison Mono Pulse” principle demonstrated here is

Ultrasonic sensors are great tools to measure distance without actual contact and used at several places like water level measurement, distance measurement etc. This is an efficient way to measure small distances precisely. In this project we have used an Ultrasonic Sensor to determine the distance of an obstacle from the sensor. Basic principal of ultrasonic distance measurement is based on

Automatic Water Dispenser using Arduino Approximately 71% of the Earth’s surface is water, yet only a meager 2.5% of it is potable. Due to increased population, pollution, and climate change, it is anticipated that we will face year-round water scarcity as early as 2025. On one side, there are already small disagreements between countries and

Arduino Project – The distance calculator I have been playing with Arduino (micro-controller) for about 2 years now and I am becoming more and more passionate about circuits. For those who are not aware of Arduino, check out my article “Arduino – A Guide for Beginners“. Recently, I was testing some new components that I

The Ping))) is an ultrasonic range finder from Parallax. It detects the distance of the closest object in front of the sensor (from 2 cm up to 3m). It works by sending out a burst of ultrasound and listening for the echo when it bounces off of an object. The Arduino board sends a short

Have you ever wanted an ultrasonic tape measure, like this Stanley? (See picture). Well, I have but then I am a Lazy Old Geek. I don’t really need one but I thought I’d try to make one. And naturally, I thought of an Arduino. August 2012 update: I just found out the software used in

Time for a follow-up to the Single Button Combination Lock by creating another oddball type of switch/lock. To activate this switch we make use of a Parallax Ping))) Ultrasonic sensor, an Arduino-style board and some other hardware – to make a device that receives a four-number code which is made up of the distance between a hand
