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 we are going to discuss how to use Ultrasonic sensor (Distance /Range Finder) with arduino micro-controller .We will be getting the object distance or range of an object on the Serial ...

Step 5: Assembling The Components. Even though we are using only the transmitter of one ultrasonic sensor and the receiver of the other, but it is mandatory to connect all of the four pins of the ...

•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 ...

So I removed this servo and IR sensors and use 3 ultrasonic sensors. With ultrasonic sensors, you can measure distance and use that information to navigate and follow a human target. Here’s a general ...

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

Primarily Ultrasonic sensor is used to measure distance from any object, but here we can see that it can be used as Security alarm or Door alarm with Arduino. Likewise we can create many useful ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.
