FAQ installation

No, normal burying and tamping of the soil is sufficient. However, always make sure that the sensor has good contact with the soil and that there are no air gaps between the sensor and the soil. Air gaps falsify the moisture measurement result.

Yes. The actively acting electrical measuring field of the sensor has a volume of up to one liter and is uniformly distributed around the sensor. The sensor should therefore not be used in planters with a volume smaller than 1 liter and should have a sufficient distance to the wall of the planter (recommended >5 cm).

No, the sensor is very robust. It does not harm the sensor if roots grow around it.

The sensor should be installed at the root depth, i.e. the depth at which the plants absorb water. For lawns, this is typically at a depth of approx. 5-10 cm.

The SMT100 and SMT50 have a measuring volume that extends in a radius of about 5 cm around the green sensor surface. The soil moisture is determined in this volume. If both the soil and the irrigation are homogeneous, then in principle one sensor is sufficient for the entire area. In the case of inhomogeneous soils, several sensors are recommended in the respective areas. One sensor is also recommended for each sub-area in the case of strong deviations in irrigation intensity.
