How to Set Up the DHT11 Humidity Sensor

2015-10-2The DHT11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your DIY electronics projects. It’s perfect for remote weather stations, home environmental control systems, and farm or garden monitoring systems. In this tutorial, I’ll first go into a

Hygrometer - Wikipedia

2018-9-13A hygrometer (/ h aɪ ˈ ɡ r ɒ m ɪ t ər /) is an instrument used for measuring the amount of humidity and water vapor in the atmosphere, in soil, or in confined spaces. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a

How to Check and Calibrate a Humidity Sensor

2017-11-30How accurate is your humidity sensor? Find out with this project. Humidity sensors are commonplace, relatively inexpensive, and come in many different varieties. Too often, we check the datasheet, use them with an interface, and (as long as the values “look reasonable”) we accept the results. In

Humidity - Wikipedia

2018-9-11Humidity is a term used to describe the amount of water vapor present in air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. The amount of water vapor needed to achieve saturation increases as the temperature increases.
