/ 3 Low-cost protective system for electronic components for monitoring water quality in fish farming. Field of invention

[001] The present invention is relevant to the field of fish farming, specifically dealing with a low-cost protection system for electronic components for monitoring water quality in fish farming. Fundamentals of the invention

[002] For the development of an automated water quality monitoring system for fish farming, it was observed that there was a need to develop equipment that would guarantee the protection of the electronic components and allow the reading of the water present in the culture tank and not just the water that remained trapped inside the equipment. A protective device for the electronic components was then developed that had a low cost, using PVC pipe, flange, cap and with the manufacture of a piece for fixing and threading in PETg material on a 3D printer. Brief description of the drawings

[003] Figure 1 shows the layout of a part model developed on a 3D printer using PETG filament for attaching probes to electronic equipment and with a thread so that the internal part of the equipment can be accessed for maintenance. Figure 2 shows the equipment. Figure 3 shows the process of disassembling the equipment to check for accumulated dirt.

[004] The initial stage of equipment development was the search for reference research on the availability of similar products on the market and the study of low-cost and accessible materials that could be used for the development of the equipment. The main considerations were the factors necessary for the protection and ease of maintenance of the electronic components, and characteristics that would allow water to flow from the tank through the protection equipment, enabling the reading of water quality parameters (temperature and pH) in fish farming tanks.

[005] Next, the equipment layout was created using a 3D printer (1), with the aim of accommodating and protecting the sensors. Regarding the assembly process, it was necessary to develop a structure composed of PETG filament and 50 mm PVC pipe. The part developed on the 3D printer using PETG filament serves to fix the probes of electronic equipment and has a thread so that the internal part of the equipment can be accessed for maintenance, and in the 50 mm PVC pipe (2), holes were adopted in an alternating and contralateral manner in the pipe support, in order to allow better circulation so that there is a reading of the real condition of the water quality of the tank and not only the liquid content inside the equipment.

[006] Upon completion of the physical equipment, a field effectiveness analysis was conducted over a period of 60 days, with the following assessments: • Verification of the developed electronic sensor protection system to ensure it allows for the reading of real water quality data in fish farming tanks; • the accumulation of dirt and the integrity of low-cost electronic sensors for pH reading; • temperature.

[007] During the experiment, temperature and pH data were read and recorded using a pH meter and an AT155® oximeter with an attached thermometer, at two times on weekdays, considered the gold standard test for this equipment. In addition, weekly visual checks were performed with photographic documentation of dirt buildup on the sensors (3), and when a covering was noted Petition 870240111490, dated 12 / 31 / 2024, page 10 / 14 / 3 Due to intense organic matter buildup on the sensors, to the point where the external surface of the probes was not clearly visible, the electronic equipment was cleaned, with monitoring occurring once every 7 days with an average time of 3 minutes for opening the equipment for maintenance. This cleaning aims to ensure that the information obtained is not significantly discrepant between the data readings from the experimental sensors and the gold standard test (pH meter and AT155® oximeter with attached thermometer).
