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 experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...

Ultrasound can be used for industrial inspection and automation - the technology is similar to the one know from medical ultrasonic imaging. Piezoelectric ultrasonic transducers also find applications ...

Piezo comes from the Greek word “piezein,” which means “squeeze” or “apply some pressure.” Whether they take form as a transducer or sensor, piezo components all operate as the result of some degree ...
