See other companies with research projects supported by PIPE ProgramNutrient concentration and liquid level information are important monitoring parameters in hydroponic systems. Whereas nutrient concentration has a direct effect on the yield and quality of plants, liquid level measurement is required to ensure nutrient water is available. Yet, growers do not instrument most hydroponic systems: either because available technology is inconvenient and expen…
Currently, most hydroponic reservoirs levels are controlled by a mechanical system. These systems use a buoy that floats above the liquid surface: when the liquid reaches a certain level, the buoy actuates a mechanical switch that either allows or stop the flow of water into the reservoir. Although inexpensive, this system has a series of problems: 1. the plant roots may cause the float …
The company intends to develop, in collaboration with the Chemistry Department of the Paulista State University (Unesp), in Araraquara, a new fiber optic sensor for determining the presence and concentration of chloride ions in concrete structures. The sensor will have a spatial resolution of up to 5 millimeters and will provide a reliable form of determining the concentration of chloride…
