Abstract
The device comprises a housing with two humidity sensors. A first opening of the housing is placed onto or into the soil, while a second opening is located outside the soil in communication with the environment. A chamber extends in the housing between the first and the second opening. This chamber allows humidity to diffuse between the openings. The humidity sensors are located to measure the humidity at two spaced apart locations within the chamber. The difference of humidity measured at these two locations is a measure of soil moisture content.
