Ultrasonic Sensor Module. There are many types of Arduino distance sensors, but in this project we have used the HC-SR04 to measure distance in range of 2cm-400cm with an accuracy of 3mm.The sensor ...

Ultrasonic Distance Measurement with Arduino This project demonstrates how to use an HC-SR04 ultrasonic sensor with an Arduino to measure the distance to an object. The distance is calculated based on ...

How the Arduino ultrasonic sensor actually works. To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate ...

When the task at hand is much simpler like obstacle detection, distance measurement, or depth monitoring, ultrasonic sensors are a great alternate to place your bets on. Not only are these sensors ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

Everything always looks good on paper (and in its seller’s description), so I plugged my module into an Arduino Prototyping Shield for a quick/lazy evaluation using an Arduino Uno. If you have played ...

•An Ultrasonic sensor and a 16X2 LCD display were interfaced using Arduino Uno R3 Microcontroller to measure the distance from the sensor to an obstacle placed in front of it.•The LiquidCrystal.h ...
