Abstract

The design of a low-cost virtual instrument to control volume and pH of nutrient solution in hydroponic plant production systems supporting life in space has been developed. The algorithms developed are computationally simple and very suitable for a single microprocessor-based LabVIEW Windows data acquisition board. The details of such a LabVIEW-based instrument are described
