M5Stack PaperColor, or M5Paper Color, is an ESP32-S3 development kit with a 4-inch E Ink Spectra 6 full-color display with a ...

UC Irvine researchers built a battery-free wearable sweat sensor that tracks multiple health biomarkers and self-regenerates.

Abstract: In the field of environmental monitoring, sensors that can quickly and accurately detect humidity play a key role. Traditional resistive and capacitive humidity sensors are difficult to ...

We studied results from our own thermostats and other research to find how much smart versions save on monthly bills -- and ...

Average body temperature is around 98.6° F (37.0° C) A fever is an elevated body temperature with these readings: Rectal, Forehead or Ear temperature: 100.4° F (38.0° C) or higher Under the arm ...

Abstract: An optical fiber Fabry-Pérot interferometer (FPI) sensor offering simultaneous measurement of temperature and pressure is proposed. This sensor is constructed by fusion splicing a ...

There’s something about the ESP32 family of microcontrollers and timekeeping. We probably see it in clocks as often as we do ...

Astrophotographers are blending IoT-based weather monitoring, precise sensors, and forecast APIs to plan and protect their imaging sessions. By uniting real-time measurements with Astrospheric ...

White clothes and linens are stain magnets. But even if you manage not to spill food or drink on that crisp white top, your perspiration and skin oils can lead to discoloration. A good detergent can ...

Arduino’s open-source platform makes it easy for makers, students, and hobbyists to build powerful multi-sensor projects for ...

Wet-bulb temperature measures the combined effect of heat and humidity, indicating how effectively the human body can cool itself through sweating. Unlike regular air temperature, it reflects the ...

When the weather gets muggy, iridescent bees shift their metallic hue. The insects are a rich blue-green when ambient humidity is low. But as the amount of moisture in the air increases, the bees turn ...
