In any industrial sector, there is a constant search for improvements in the production process. Process automation has become the greatest ally, as it offers greater productivity in less time, reduces human work and reduces product waste. However, the high prices of equipment becomes a risky investment, since, according to SEBRAE, high investments without planning and lack of capital result in the bankruptcy of 80% of micro and small companies before completing 1 year, that is, , in its initial phase. Thus, the present work describes the development of a low-cost semi-automatic liquid filling machine, capable of filling pre-set quantities, using containers of different sizes. The project is aimed at improving the production process of small companies in the initial phase, in the cleaning materials sector that work with liquid products, such as disinfectants, alcohol, bleach and glass cleaner. We sought to use components that are easy to access and low cost, in order to make maintenance simple and make the prototype cheaper. Among the components used, the load cell stands out, consisting of resistive strain gauges coupled to a metallic structure which deforms according to the applied force, making it possible to measure quantities such as force and pressure. A prototype was built, which met the sufficient tolerances for the liquid filling process, in accordance with INMETRO Ordinance No. 248/2008, proving to be a great option, in view of the presented precision, agility in the filling process and the reduction of product waste.

Sports considered extreme are differentiated by containing a high risk and adventure. These risks can be low or even risks considered very high. Skydiving, for example, is considered a high-risk sport that is susceptible to interference from weather conditions. Skydiving is a sport that promotes sensations of pleasure as is the case with skydiving. Therefore, this project intends to contribute, through a device, to a better analysis and interpretation of climate changes that occur during the practice of skydiving, before and during the jump. Then, the construction of a control device through the Arduino platform was carried out, integrated to the internet in real time to obtain data and weather conditions. For bibliographic search purposes, the Google Scholar tracker and the electronic addresses of the Brazilian Parachuting Confederation (CBPq) were used as a tool, to complement this work with more information. Based on research and studies carried out, it was found that currently there is no rule or devices used in skydiving schools to help skydiving athletes to recognize the best conditions for jumping. It is pertinent to emphasize the lack of studies and the difficulty encountered in carrying out experimental research within skydiving. Finally, it can be said that a greater participation of professionals in the areas of technology is necessary, aiming at the development and growth of the sport.

The use of renewable energies is being used more and more in Brazil and in the world, especially solar energy to generate electricity. This is a trend currently observed and one of the major factors for this is the possibility of obtaining a large cost reduction with the use of photovoltaic electricity detected with traditional electricity. In addition to the ease of producing clean energy, without noise in its generation, it has the practicality of being installed in any place that has sunlight and availability of space for the installation of the photovoltaic system, which can be on roofs, land and to parking lots. This last location is increasingly protected in its use, because while it protects cars from the sun's action, it also generates electricity through its cover with photovoltaic panels, also helping in the Brazilian energy matrix. In 2022, the share of photovoltaic energy in the Brazilian energy matrix was 4.3%. On 09/03/2023, Brazil consumed the mark of 6,044 MW, a record in solar energy generation. This happens in the midst of so many climate changes that increasingly face sustainable development solutions and investments in resources for the use of renewable energies such as photovoltaic energy. In this context, this study intends to analyze the technical feasibility of implementing a solar photovoltaic parking lot connected to the electrical grid to transform solar energy into electrical energy in the IFAM-CMDI, using the PVSyst software, a computational tool to verify the numeric values of the study and assistance in the development of a photovoltaic project. The methodology applied was through a case study on the implementation of the photovoltaic solar system connected to the grid (on grid) with a bibliographical review on the subject, data collection for system sizing analysis, reading and interpretation of technical data of the system components. The results obtained from the technical study of the implementation of solar parking optimized through PVSyst obtained an excellent result, concluding that the implementation of solar parking at the IFAMCMDI is technically feasible.

Brazil is one of the countries with the greatest potential for absorbing energy from the sun due to its location being close to the equator. Previous studies already carried out apply to only estimating this potential using data on irradiation levels, while few studies have con-ducted statistical modeling with software that incorporates various types of photovoltaic mo-dules of current inverters and their efficiency,system losses and data on local weather condi-tions. The Software (SAM) calculates the performance of photovoltaic systems based on local climatic conditions and data entered into its database of all components with their respective model and manufacturer to carry out the computational calculation. It is, therefore, a very effective tool for determining the viability of a photovoltaic project before its implementation and afterwards for energy estimation. The main objective of this work is to use SAM to esti-mate the energy production throughout the year of the 9 photovoltaic generators installed on the roof of IFAM-CMDI and consequently point out if there is any incompatibility between the simulated generation and the one generated on site that was extracted by the remote mo-nitoring software for GOODWE inverters.

Climate monitoring is a fundamental parameter for various fields of knowledge, as climate changes directly impact peoples quality of life. In this study, low cost sensors for temperature, relative air humidity, atmospheric air pressure, air temperature, and altitude were utilized. These measurements were compared with commercial sensors for temperature and relative air humidity (HOBO®, pendant); atmospheric air pressure (HOBO®, RX3000); and air temperature (HOBO®, RX3000). The low cost ESP32-S weather station was installed on the campus of the Instituto Nacional de Pesquisas da Amazônia (INPA) to compare its data with the 80m station data from the IETE monitoring network, verifying the measurements and attesting to their accuracy. To assess the performance of ESP32-S sensors, descriptive statistics (MBE), Root Mean Square Error (RMSE), and the coefficient of determination (R²) were applied. From the analysis of the obtained data, it was observed that the temperature values from the low cost station underestimated both daily maximum and minimum values, with an MBE of -0.59 °C and a spread of 0.59°C (RMSE). Humidity showed differences of 21.03%, with a spread of 19.47% in both the temporal series and daily cycle. Pressure values consistently underestimated throughout the daily cycle, where atmospheric pressure measured by BMP280 captured the pressure variability but overestimated compared to the measurement by HWS S-BPA-CM10, with an MBE of 2.8 hPa and a spread of 2.8 hPa. Although the observed error for humidity has a larger amplitude of over 20%, the agreement between the data is still strong with a value of 0.9. The agreement for air temperature and atmospheric pressure showed values of 1 and 0.99, respectively. Therefore, the use of a low cost weather station can be considered viable, both in terms of cost and in producing results equivalent to those of commercial weather station sensors.

The waste generated by the disposal of various types of electronic waste significantly impacts the environment. In small electronic projects for didactic purposes, the making of the tracks of a circuit on a phenolite board, are usually produced by hand, through the corrosion process, using iron perchloride (FeCl3). However, this solution has a considerably short lifespan and can be reused an average of five times, having to be discarded, however, most of the time this disposal is carried out in inappropriate places. And it is at this point that the present work is inserted, which aims to propose the implementation of a system at the IFAM-CMDI, which aims at the disposal and recovery of iron perchloride, so that it can be reused, in order to avoid its inappropriately dumping into the environment.
