Arduino Nano R4 pinout diagram Two SKUs are offered for the Arduino Nano R4: ABX00143 with headers ideal for breadboard projects ($13.30) and ABX00142 without headers ($12.10) to solder the board to a ...

A simple electrode configuration of piezoelectric ultrasonic sensor has been proposed and the sensitivity has been improved. The new electrode configuration enables to use two parts of both the ...

To experimentally study the characteristics of ultrasonic sensors, a wideband air-coupled ultrasonic transducer, wideband electromagnetic dynamic acoustic transducer (WEMDAT), is designed and ...

Seven of the sensors use electrochemical detection, while one uses optical detection. The study, published in the journal Langmuir, describes the development of an electrochemical sensor chip for the ...

An obstacle-avoiding robot using an ultrasonic sensor and motor control, programmed with Arduino to autonomously navigate and avoid obstacles by stopping, reversing, and turning.
