PlantCare Mini-Logger

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.

Measuring range soil moisture (at a soil temperature between 2° C to +37° C*):

- Relative %-units: 0 - 100%

- hPa: 0 – 400 hPa high sensitivity / > 400 - 800 hPa lower sensitivity

Measuring range soil temperature: -20°C to +50° C

Measuring accuracy:

- Soil moisture: +/- 3%

- Soil temperature: +/- 0.3° C

Reading accuracy:

- Soil moisture in relative %: 1%

- Soil moisture in hPa: 1hPa

- Soil temperature: 0.1 °C

* Sensors for soil moisture measurements at soil temperature range between 2° C to +50° C on request

 

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.
