Universal control is a neat feature on Macintosh computers, allowing you to slide your mouse seamlessly from device to device. Of course you need a relatively recent version of MacOS to make it work, ...

Arduino Library for the SparkFun Air Quality PM1/PM2.5/PM10 Sensor - BMV080 The SparkFun Air Quality PM1/PM2.5/PM10 Sensor - BMV080 (Qwiic)is an ultra-small, fan-less air quality sensor for sensing ...

Humanity pretty much has Pi figured out at this point. We’ve calculated it many times over and are confident about what it is down to many, many decimal places. However, if you fancy estimating it ...

"ESP32 eInk Room Node" — battery‑efficient Wi‑Fi sensor node with a 2.13" mono e‑ink display. Wakes on a schedule, reads inside sensors, pulls outside stats (from Home Assistant or MQTT), renders to e ...

Abstract: This study experimentally examined the energy usage of the ESP32 and Arduino Nano microcontroller boards in active and deep sleep (power-down) modes. Both boards were powered by a continuous ...

Abstract: In this article, we propose a digital encoding sensor network based on the electromagnetically induced transparency (EIT) effect for industrial multipoint temperature monitoring applications ...
