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

Basically, this program enables the Arduino UNO R4 to connect to an existing WiFi network, so it can send an SMS alert via API when the flame sensor or smoke sensors detects fire and smoke. At the ...

If those seem familiar, it’s because the seven modules were sold as part of the Arduino Plug and Make Kit with an Arduino Uno R4 WiFi. So they are not exactly new, and the main change is that they can ...

Labeling bottles manually takes a good chunk of time and effort. Addressing this, the YouTube channel Easy Home Made Projects has developed a DIY automatic labeling machine using an Arduino Nano, a ...

Abstract: Context-centric sensor-based proximity detection (or, contextual co-presence detection) is a promising approach to defend against relay attacks in many mobile authentication systems, ...

Abstract: Airborne transmittable diseases such as COVID-19 spread from an infected to healthy person when they are in proximity to each other. Epidemiologists suggest that the risk of COVID-19 ...
