This project shows a super easy way to get started with your own DIY Multisensor to use with Home Assistant, a sick, open-source Home Automation platform that can do just about anything. This code ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...

IKEA has launched its new Gömpyssling LED light with sensor. It's a motion-activated light which automatically switches on when you open a cupboard or step into a space, then turns itself off after ...

SwitchBot has launched its new battery-powered Presence Sensor, featuring a 60Hz mmWave radar, PIR sensor and light sensor. It offers continuous, highly accurate presence detection and has up to two ...

Rutronik Adapter Board RAB7 is an open-source hardware Arduino shield designed for AI-powered Sensor Fusion with seven environmental and inertial sensors from Bosch, Infineon, and Sensirion. The ...

ABSTRACT: This study investigates the optimization of Fresnel lens designs using Zemax software, with a focus on minimizing beam divergence by controlling the output spot diameter on the image plane.

A team of CU Boulder researchers has introduced a quantum sensing technique that could lead to improvements in how we monitor infrastructure, detect changes in the environment and conduct geophysical ...
