Automação do controle e do monitoramento de temperatura e umidificação de canteiros de cogumelo Agaricus blazei, no cultivo familiar em Santa Helena/PR

Abstract

Family farming has great relevance when presenting the numbers of Brazilian food producing properties that supply the domestic market. In this scenario, we highlight the cultivation of mushrooms that can supplement income for small producers, due to the use of small spaces and good market acceptance. The A. blazei mushroom is a fungus consumed due to its medicinal value and the strengthening properties of the immune system. The cultivation of this type of fungus has specific characteristics of care, such as the constant monitoring of humidity and temperature, fundamental abiotic factors that can enable the good performance of the crop. In view of this, this work proposes the automation of the control and monitoring of temperature and humidity by means of sensors and microcontrollable devices, at affordable cost for the family agriculture, propitiating the reduction of the workmanship of the farmer. The Arduino platform was used for this purpose. The experiment was carried out in two phases, manual and automated, in order to compare the results and identify the productivity and the best form of cultivation, as well as the ideal humidity for the development of the crop in the region where the experiment was carried out. The beds in which the humidity and temperature sensors were installed showed facilities to handle the harvest. The second automated harvest showed a yield of 59.86 kg, with 4.31 kg of A. blazei mushroom in natura more than the first manual phase. The A. blazei presented better performance at the site with humidity close to 80%, with a standard deviation of 1.13. In this scenario, it is verified that the region in which the experiment was performed presents propitious conditions for the cultivation of A. blazei mushroom. The information was sent via Internet connection to the Thingswo Internet Things (IoT) web platform for data storage, which enabled the identification, monitoring and follow-up of the aspects of A. blazei growth at a distance. It concludes the work that the use of sensors and microcontrollers facilitates the production, identification of the best moisture for the development of the cultivar and reduces labor costs.
