Fidget toys are everywhere these days. A particularly popular type simply puts some keyboard switches on a plate to provide a certain type of clicky satisfaction. [wjddnjsdnd] took that concept a ...

Overcurrent relays with inverse definite minimum time (IDMT) characteristics are widely used in power systems to protect ...

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

Abstract: Optical fiber displacement sensors are extensively used in pre-warning of landslide and earthquake. Here, we propose a highly sensitive microdisplacement sensor based on sidewall resonance ...

Abstract: This work studies a magneto-optical surface plasmon resonance (MOSPR) sensor design that uses the photonic spin Hall effect (PSHE) concept, including cerium-substituted yttrium iron garnet ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...
