Computer Technology
Computer technology is an integral part in the production of hydroponic spinach. Different sensors are used to monitor greenhouse environment parameters. These parameters include temperature of greenhouse air and nutrient solution, relative humidity and carbon dioxide concentration of greenhouse air, light intensities from both sunlight and supplemental lighting, pH, Dissolved Oxygen (DO), and Electrical Conductivity (EC) of the nutrient solution.
