This project documents the design and implementation of a low-cost infrared (IR) transmitter and receiver system suitable for industrial wireless communication. Developed using off-the-shelf ...

For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop. That outputs both the audio signal and a 40 kHz carrier signal, implemented using the ...

Overview Hydrosmart is an advanced water level monitoring system that leverages wireless communication, a touchscreen interface, and real-time data visualization to control and monitor water levels ...

Compared to the original mechanically tuned variable frequency oscillator in the Drake receiver, the direct-digital synthesis method promises more stability, meaning less knob-nudging to stay on ...

Resonant tunneling diode (RTD) oscillators are considered promising candidates for developing novel terahertz electronic devices owing to their capability of ultrahigh-frequency operation. Here we ...
