High-Precision Soil Sensor
Koubachi Wi-Fi Plant Sensor 2 Pro was developed at ETH (Swiss Federal Institute of Technology Zurich). Our patented soil moisture sensor measures water potential (hPa) in all substrates. No calibration required. The matrix potential sensor - similar to a tensiometer - measures the soil moisture tension. It determines the quantity of water that is actually available to the plants' roots regardless of the soil type and soil conditions. Each Plant Sensor 2 Pro leaves our factory checked for extra high quality pre-calibration.
