Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

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 ...

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 ...

In industrial automation, sensors are not just accessories, they are critical components that directly affect machine performance, operator safety and production efficiency. A poorly selected sensor ...

Since the backlight of the LCD panel in a smartphone accounts for around 40% of the device’s total power consumption, one can benefit greatly by adjusting the brightness in response to changes in ...

Researchers have discovered an extraordinary diversity of opsin genes that encode light sensors involved in color vision in dragonflies. We humans have a trichromatic color vision based on three opsin ...

Even the faintest trace of hydrogen gas can spell trouble. In a chemical plant, it may auger a catastrophic industrial explosion; on a patient’s breath, it can signal various gastrointestinal problems ...
