The Skye EvapoSensor consists of 2 black 'leaf' elements, one dry and one kept wet via a wick and water reservoir.
The temperature of these 2 'leaves' are measured individually and the temperature differential is measured.
The 2 simulated leaves are affected by their local environment just like plant leaves,and react to the four weather factors which drives water loss from plants,namely relative humidity,air temperature,wind speed and solar radiation.
