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 ...

If you have one ultrasonic ... or the distance traveled by a tablet along a rail. If you have two sensors and a microcontroller, you can pinpoint any object within a defined range using trigonometry.

In the real world, missile systems use advanced radars ... To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates ...
