a solid contact probe and an ultrasonic emitter that helps locate faulty seals, gaskets and weatherstripping in doors, windows, ductwork and other non-pressurized enclosures. All components are packed ...

This project primarily uses the principles of ultrasound waves and their propagation through air to determine the coordinates of the stylus. The project also uses peripherals such as Wide timers, PWMs ...

Developed a system based on Raspberry Pi 4 that detects the presence of a cat near a vehicle using infrared (IR) sensors, and triggers an ultrasonic sound emitter to deter the cat. The system should ...

and various ultrasonic wave emitter conditions. By extracting the key features of the acoustic signals, such as the peak time, propagation time, and peak amplitude, an accurate inversion of the ...
