Recently an ad on YouTube about an acoustic light sensor/switch module piqued my interest. Out of curiosity, I contacted the online vendor and bought a pair. Named MR-SK50A, the module is less popular ...

Light sensors often use an infrared LED as a light source. Infrared LEDs have a greater intensity than LEDs that emit visible light. And when infrared photodiodes are used the sensors are relatively ...

You’re probably familiar with those regular old light switches that you fumble for in the dark, but maybe you’re unclear on what a smart switch is. Good news: you’ve come to the right place. A smart ...

Two omnipolar magnetic switches from Littelfuse combine tunneling magnetoresistance (TMR) and CMOS technologies in a compact LGA4 package.

The Instinct Wi-Fi light switch features built-in sensors for motion and ambient light, as well as a microphone and speaker for your Alexa commands. Originally hailing from Troy, Ohio, Ry Crist is a ...

Ambient light sensors (ALSs) are photodetectors that approximate the human eye’s response to light intensity under a variety of lighting conditions and through different attenuation materials. They’re ...

There are as many varieties of smart light switches (and dimmers) as there are light bulbs, and while the prospect of upgrading your old dumb switch might seem daunting, they’re usually pretty simple ...

A pioneer in digital imaging, Sony announced its first stacked CMOS sensors for full-frame cameras back in April 2017 on the flagship Sony A9 camera. A stacked CMOS sensor captures significantly more ...
