In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing addressable LEDs. In this case, I'm using an Arduino uno (clone board) and a ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators ...

If you’ve ever had your internet connection drop out while running Chrome, you’ve probably seen a little dinosaur pop up to tell you what’s going on. You might have then tapped a ...

CMU researchers paired acoustic resonance sensors with machine learning to create a controller that is easier to manipulate than traditional models and could help people with limited fine-motor skills ...

Abstract: This paper proposes miniaturized, lightweight and ultrasensitive planar metamaterial sensor for relative permittivity measurement of nondispersive materials. The proposed sensor is designed ...

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), ...
