A simple soil moisture sensor for gardeners. Soil moisture sensors measure the volumetric water content in soil. [1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant ...
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
Capacitance hygrometers are not affected by most volatile chemicals and can be much smaller than other alternative sensors. They do not require cleaning, but are less accurate than dew point hygrometers (+/- 0.015 a w). They should have regular calibration checks and can be affected by residual water in the polymer membrane (hysteresis).
Global Open Data for Agriculture and Nutrition (GODAN) is an initiative that seeks to "support global efforts to make agricultural and nutritionally relevant data available, accessible, and usable for unrestricted use worldwide. The initiative focuses on building high-level policy as well as public and private institutional support for open ...
Most of ResearchGate's users are involved in medicine or biology, [10] [12] though it also has participants from engineering, law, computer science, agricultural sciences, and psychology, among others. [10] ResearchGate published an author-level metric in the form of an "RG Score" since 2012. [15] RG score is not a citation impact measure.
The psychrometric ratio is an important property in the area of psychrometry, as it relates the absolute humidity and saturation humidity to the difference between the dry bulb temperature and the adiabatic saturation temperature. Mixtures of air and water vapor are the most common systems encountered in psychrometry.
