Abstract
This invention relates to a device that may be inserted into the soil of a potted plant for the purpose of determining the soil moisture content thereof. The device employs a moisture sensitive signalling element and a tube-shaped humidity chamber which provides means for establishing an equilibrium condition between the moisture content of the soil and the moisture content of the air surrounding the signalling element, thereby providing an accurate indicator of soil moisture content.
