I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

Simple Arduino Sine Wave Generator This project is a simple, variable-frequency sine wave generator built on the Arduino platform. It uses Pulse-Width Modulation (PWM) to produce a digital ...

Human physiological signals play a crucial role in the fields of health assessment, sports medicine, and human–computer interaction. However, human vibration signals exhibit a wide frequency range and ...

The article proposes an innovative solution for electric heating systems of large areas at considerable distances using piezoelectric temperature sensors based on resonant frequency measurement. The ...

The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a ...

A research team at Los Alamos National Laboratory recently found that the strength difference between two very high-frequency radio pulses in lightning is closely related to the altitude of the ...

Renasas RA4C1 microcontroller (MCU) group is based on an 80-MHz Arm Cortex M33 core and designed for utility meters and ...

A radio frequency sensor they developed observed more than 76,000 TIPPs, matching them to lightning detected from the ground aboard a satellite in geostationary orbit.
