Bermuda enables device proximity in a room without using any trackers or apps. Using an ESP32, it works as a Bluetooth proxy, ...

Abstract: In this work, a sensor based on a modified porous aromatic framework (PAF-1-S) was successfully fabricated for humidity detection. The prepared sensor possesses promising sensing performance ...

Having an enclosed 3D printer can make a huge difference when printing certain filaments that are prone to warping. It’s easy enough to build an enclosure to stick your own printer in, but ...

Getting started with Arduino can feel quite overwhelming at first because you're faced with the decision of what board to buy ...

Abstract: A highly sensitive humidity sensor based on open cavity fiber Fabry-Perot interferometer (FPI) with double-sided contact film is proposed. The sensor is fabricated by inserting a section of ...

There are a lot of options for local weather stations; most of them, however, are sensors tied to a base station, often requiring an internet connection to access all features. [Vinnie] over at ...

The HX710(A/B) is a precision 24-bit analog-to-digital converter (ADC) with built-in temperature sensor (HX710A) or DVDD, AVDD voltage difference detection (HX710B). It’s designed for weigh scales and ...
