- Abstract
- The article proposes a variant of remote control of the nutrient mixture for hydroponic installations based on Arduino. Taking into account the analysis of the capabilities of Arduino, the specific task being solved and the material costs, a choice of components was made. When using the device, after some time, the conductivity sensors need to be calibrated, since oxidation occurs at the anode during electrolysis. For this class of installations, an effective and economical option for cleaning the conductivity sensor from oxide films is proposed, which increases the operating time without additional calibrations.
