An Algerian research team has developed a smart water-spray cooling system for PV panels that activates only when temperatures exceed a set threshold, boosting efficiency while minimizing water use in ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of ...

Researchers developed a super tiny thermometer that sits directly on a chip could monitor temperature changes and potentially ...

Wearable devices are often exposed to environmental variables that can significantly impact temperature readings. A smartwatch sits on the wrist, where ambient air temperature, sunlight, and even wind ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Thermoregulation is the process by which the body maintains a steady internal temperature. The thermoregulation system includes the hypothalamus, sweat glands, circulatory system, and skin. The three ...
