Vapour-Pressure Deficit Virtual Sensor

Vapor-pressure deficit (VPD) is one of the methods growers use to measure humidity in a greenhouse or growing environment. It allows growers to gauge the impact of humidity on plant growth and development.

VPD in Aranet Cloud is calculated according to the formula:

Required measurements:

The default metric of VPD is kPa.
