PlantCare Mini-Logger nat. 18 cm
Soil moisture and soil temperature monitoring system
The PlantCare Mini-Logger is a maintenance-free sensor which records soil moisture and soil temperature. A USB stick is used to easily program the mini-logger and readout the data. The PlantCare DataViewer Software allows a quick and easy display and analysis of the measured data. Fields of application are scientific research, agriculture and garden and landscaping construction.
Benefits PlantCare Mini-Logger

Measuring method PlantCare's worldwide patented sensor technology is based on the microthermic measurement of soil moisture. A specially developed felt material in moisture balance with the soil acts as the interface between the surrounding soil and the sensor. To measure the moisture level, the sensor is briefly heated and the cooling-down time, which varies depending on soil moisture, is determined. The sensor's cooling-down time thus provides a reliable statement of the soil's moisture content. Technical specifications
