Monitoring pH in hydroponic cultivation is crucial for plant health and optimal yields. Plants can only absorb all necessary nutrients within a specific pH range. Outside of this range, nutrients cannot be fully absorbed. Therefore, constant monitoring of pH is essential to prevent nutrient deficiencies.

The sensor’s electrode is composed of a pH-sensitive glass membrane and an internal reference electrode. Both are essential for measuring the pH of a solution. The glass membrane responds to variations in the concentration of hydrogen ions, while the reference electrode provides a stable reference point, enabling the determination of pH. Thanks to its robustness and versatility, the electrode is ideal for measuring pH even in contaminated liquids and requires calibration checks approximately every 4 months.

The display transmitter provides real-time readings directly in the greenhouse, ensuring highly accurate data. The radio transmitter converts the electrode data into radio waves and transmits it wirelessly to the Base Station.
