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 ...

Shifting to the new waterproof ultrasonic sensor is not a big deal, since it’s pretty easy to modify some example codes to use it. The quick road test, oh it’s a simple approach to display the ...

[Guido] found out how intermittent the reliability of the ultrasonic sensor was and came up with a clever way to smooth out its output in order to get more accurate readings from it, using a ...
