This library (with example) is designed to be integrated in projects using ultrasonic proximity sensors. It was tested with HC-SR04 device but it should be usable with equivalent sensors which have a ...

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 ...

The ultrasonic sensor measures the distance of the nearest object, sending the result to the serial port. It can work from 2 cm to 3 m. It measures the time spent by the signal to reach the object and ...

The following article shows you how to interface the SR04T Waterproof Ultrasonic sensor with an Arduino Uno to obtain distance data. The article also discusses the working of the module along with a ...

I will use this sensor (or its latest version) in a more complex project in the next part of this post. Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the ...

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 ...
