This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional ...

The PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup(). It is possible to add a sensor (pin) ...

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 ...

Boardcon EM1103B is an AIoT SBC powered by a Rockchip RV1103B SoC designed for surveillance applications with dual camera, fingerprint, and a PIR sensor. This unique combination makes it suitable for ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

Companies have been trying to make augmented reality glasses a thing for more than a decade, but the product category has yet to take off. But Meta thinks it might be close to cracking the code.

In recent years, advances in photonics and materials science have led to remarkable developments in sensor technology, pushing the boundaries of what can be detected and measured. Among these ...

The FP1E’s millimeter wave technology provides for a much more nuanced look at whether a room is occupied or not, but you’ll need one of Aqara’s Zigbee or Matter smart home hubs to use it. Whatever ...
