This project is an advanced 4-channel relay module designed for home automation and IoT applications. Unlike standard relay boards, this design integrates an LM2596 buck converter for onboard ...

Abstract: High-frequency sine wave gating (SWG) InGaAs/InP single-photon detectors (SPDs) are widely used for synchronous near-infrared single-photon detection. For practical use, the size of SPD is ...

Abstract: Supercapacitors-based power supplies are becoming increasingly common for applications that demand rapid and significant power fluctuations. To effectively evaluate their benefits and ...
