This paper presents a 591×438-DPI ultrasonic fingerprint sensor. The sensor is based on a piezoelectric micromachined ultrasonic transducer (PMUT) array that is bonded at wafer-level to complementary ...

Weather stations are a popular project for experimenting with various environmental sensors, and for wind speed and direction the choice is usually a simple cup anemometer and wind vane. For [Jianjia ...

This simple to construct water fishing thermometer circuit is intended to be used in sports applications like for example a fishing contest. A sensor measures the water temperature at a certain depth.

It has become a common sight, a must-have feature on modern cars, a row of ultrasonic sensors embedded in the rear bumper. They are part of a parking sensor, an aid to drivers for whom depth ...

Microcontrollers come in all sorts and sizes, and it’s very tempting to use them everywhere. If you are in a plan to build your own Vending Machine, probably you need a microcontroller-compatible Drop ...

The Google Pixel 9 series is here, and one of the biggest upgrades it delivers is the use of a new ultrasonic fingerprint sensor, and it’s the same one used in Samsung Galaxy devices. In the “Tensor ...
