This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

Here’s something fun from [Chad Kapper] over on HackMakeMod: Escape Room Lockbox with the Cheap Yellow Display. You may have heard of the “cheap yellow display” (CYD), so-called due to the board’s ...

Extend the LM358 op-amp family’s output voltage range by cascading the op-amp with a few simple, inexpensive components.

Hot glue guns are pretty simple beasts: there’s an on/off switch, a heating element, and a source of current, be it battery or wired. You turn it on, and the heater starts warming up; ...

MEMPHIS, Tenn. - Make sure to have the heavy coat and sunglasses. It's a frigid start to the day under a mostly clear sky. Temperatures this Thursday afternoon will be near 40 degrees across the ...

MEMPHIS, Tenn. - There's a Level 1 out of 5 threat for isolated strong storms Friday night. Have the umbrella if you're up and out before morning rush hour. Northern Mississippi has the best chance ...

As mercury thermometers are a thing of the past, you no longer have to wait several minutes to read a small red line. Instead, there are now five different types of thermometers — rectal, oral, ...

The IM19 is used in conjunction with the UM980 GNSS receiver to provide tilt-compensated Lat/Lon/Alt readings with 1cm accuracy up to 30° tilt angle, and 2cm accuracy up to 60°. Various bits of the ...

Abstract: This work discloses a temperature sensor based on a polysilicon microelectromechanical systems (MEMS) resonator. The system exploits the temperature drift of the resonance frequency of two ...

Abstract: This paper reports a miniaturized temperature sensor based on ruthenium oxide with low resistance and high sensitivity at cryogenics. The ruthenium oxide thin films were prepared by ...
