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 ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

Ultrasonic sensor transducers work well in medical applications such as patient monitoring, flow measurement and air bubble detection used in infusion systems, pharmaceutic devices or spirometry.

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 ...

Piezoelectric crystals are a class of materials that exhibit a unique property called piezoelectricity. These crystals generate an electrical charge when subjected to mechanical stress or strain, and ...
