Tiny thermometers offer on-chip temperature monitoring for processors
The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of which can overheat under stress, causing steep drops in performance. To ...
At first glance, it may look like [Rybitski]’s 7-segment RGB LED clock is something that’s been done before, but look past the beautiful mounting. It’s not just stylishly framed; ...
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 ...
This is the Sensirion SFX6XXX library for Arduino allowing you to communicate with a sensor of the SFX6XXX family over UART using the SHDLC protocol. Click here to learn more about the Sensirion ...
Abstract: Global warming and the associated increase in heatwaves have made the prevention of heat-related illnesses such as heatstroke a critical global challenge. Monitoring physiological indicators ...
Abstract: A highly sensitive and stable temperature sensor based on a diamond-Ga2O3 Schottky-p-n diode is demonstrated in this work. The forward current exhibits a pronounced temperature dependence, ...
