The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...

The Arduino UNO R4 will detect fire or smoke using the specific sensors and trigger the SMS alert to the authorized person’s mobile number. It is a simple, low-cost way to improve safety in your house ...

Abstract: We report on what we believe to be the first truly distributed fiber vibration sensor based on pulse base Brillouin optical time-domain analysis (BOTDA). The pulse base approach is used to ...

We present a BOTDA system based on dark-pulse scattering that provides improved resolution, accuracy, and acquisition time over conventional BOTDA systems, without the severe limitations on sensing ...

This library supports only one DS18B20 per Arduino/ MCU pin. If you need more functions or ... with relatively few problems when you need more functionality like multiple sensors on one pin. Finally ...

The micro sensor showed quick, stable, and high sensor responses to toluene at ppm (parts per million) concentrations at 300 °C even by operating the micro heater in a pulse-heating mode where ...

The pulse oximeter, a device that measures the degree to which red blood cells are saturated with oxygen, is one of health care's most fundamental tools. Nov 15, 2024 0 ...
