It's why DIY smart home projects suddenly got cheap (and actually doable) ...

The ESP32 does everything a Pi Pico does, but costs less and lasts 100x longer on batteries ...

There are plenty of drones (and other gadgets) you can buy online that use proprietary control protocols. Of course, reverse-engineering one of these protocols is a hacker community classic. Today, ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

The best smart thermostats we've tested can control your home's heating and cooling with your phone or voice—and might help you save on energy costs. I’ve been working with computers for ages, ...

Abstract: In this work, we present a high-sensitivity fiber-optic temperature sensor based on the enhanced Vernier effect. The sensor consists of a cascade of three Fabry–Perot interferometers (FPIs), ...

Abstract: The paper proposes an S-shaped fiber Surface Plasmon Resonance (SPR) sensor structure capable of simultaneously measuring refractive index (RI) and temperature for the first time. The ...
