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 ...

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. - Cold and dry conditions will stick around through Tuesday morning. The coldest period will be early Monday, when wind chills could drop into the 10- to 15-degree range, especially ...

It is a truth universally acknowledged that a man in possession of a good e-ink display, must be in want of a weather station ...

The best smart thermostats we've tested can control your home's heating and cooling with your phone or voice—and might help you save on energy costs. I’ve been working with computers for ages, ...

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, ...

Abstract: Temperature and humidity levels inside pharmaceutical packaging can significantly affect the shelf life of the enclosed medications. The RFID technology in the UHF band is promising to ...

The HX710(A/B) is a precision 24-bit analog-to-digital converter (ADC) with built-in temperature sensor (HX710A) or DVDD, AVDD voltage difference detection (HX710B). It’s designed for weigh scales and ...

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