An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...

The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...

As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP30 provides more detailed information about the air quality. Download all the source files and open examples ...

which contains both the humidity sensor and the readout circuit. The sensor is constructed using the polyimide passivation layer and the top metal layer available in the technology used. Power and ...

A capacitor type of hygrometer is usually used to measure relative humidity. The sensor has a dielectric polymer layer that absorbs water molecules from the air through a thin metal electrode.

The Raman and optical transmission spectra verified that the graphene sample is bilayer. The responses of the bilayer graphene sample increased with increased relative humidity.

I learned how to use IoT devices like Arduino, humidity sensors, and temperature sensors to collect useful data. I even made better visualizations than what ThingSpeak offered, which helped me ...
