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.

Recently I was looking for an inexpensive pressure + temperature sensor for a barometric altimeter project, which then led to me finding the SPL07-003. After learning there was no existing library to ...

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; ...

Evening rain showers are followed by clearer skies and colder conditions overnight. A cold blast arrives for MLK Weekend. Saturday will be partly to mostly sunny and cold. Saturday night will be ...

Abstract: Temperature greatly influences the activity of biological materials; therefore, it is necessary to simultaneously monitor the temperature and concentration of biological materials.

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 ...

Find historical weather by searching for a city, zip code, or airport code. Include a date for which you would like to see weather history. You can select a range of dates in the results on the next ...
