The SRF01 is a popular ultrasonic sensor used primarily for range finding applications. [Jaanus] discovered that they had a few flaws, including not working after being dropped. The faulty ones began ...

An ultrasonic sensor is a type of electronic device that measures the distance to an object using ultrasonic sound waves. It works by emitting high-frequency sound waves and measuring the time it ...

Focused high-frequency acoustic waves are utilized in industrial non-destructive testing (NDT) on account of their exceptional spatial resolution and high sensitivity. However, the majority of the ...

This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is ...

Amphenol has bought Airmar Technology, a US developer of ultrasonic transducer and Chirp technology. Ultrasonic transducer maker Airmar is now part of the Amphenol Interconnect and Sensor Systems ...

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 ...

The simple acoustic field generated by conventional transducers limits the development of ultrasound applications. Current methods rely on passive acoustic lenses or active arrays to manipulate ...

Ultrasonic levitation is by now a familiar trick: one or more ultrasonic transducers create a standing wave, and small objects can be held in the nodes of this standing wave. With a sufficiently large ...

Ultrasonic sensors are widely used in various applications for distance measurement. The HC-SR04 sensor, in particular, is popular due to its accuracy and ease of use. In this article, we will learn ...

Infineon Technologies has developed what it says is the first single chip capacitive MEMS ultrasonic transducer for embedded switches and medical sensors. The size reduction of the capacitive ...

Dr. Park Chan Wook (Postdoctoral Researcher, Non-Destructive Metrology Group, KRISS); The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic ...
