The project arises in articulation with others already existing or in implementation and consists of creating a system capable of (through sensors and actuators) watering the plants of a pedagogical greenhouse, when necessary; Able to warn / act when plants are exposed to excessive temperatures, too little or too little sun, excessive humidity or lack thereof.
This system will be based on the Arduino board which, with the help of various sensors and other mechanisms will control the environment of the greenhouse.
Also create a program that will interact with the system described above, where you can change the parameters of the greenhouse. In this program it will also be possible to visualize the status of each sensor / actuator to detect if one is damaged.
The greenhouse will be constructed using materials, if possible recovered / reused, such as metals and plastics.
In a Biology and Geology class, the students of the 11th grade, with the help of Professor Magda Guimarães, proceeded to the study of a soil sample previously collected by the students of the Professional Course of Technician of Management and Programming of Computer Systems. After properly separated by the sieves used, weighed and calculated the percentages of the various constituents of the soil according to the size of the particles, the students came to the conclusion that the soil can be classified as free sand, according to the classification instruments presented here.
Sowing was started on three soils of different origin, maintaining the soil, however, classified as free-form sand and collected on the school grounds, as one of them. In order to verify, in comparative terms, if the soil of the school enclosure studied from the point of view of the size of the particles that constitute it, presents the same potential for the development of plants of parsley than other soils obtained by composting, we will control the levels of humidity and exposure to sunlight, with the available sensors.
Participants in the launch of "Seeds to land" were the students of 9ºB accompanied by the Natural Sciences teacher, Alexandra Santos, and the previously studied concepts on abiotic factors were recalled. Some students mentioned that in the "grandparents' garden" there is also a parsley, but there is no possibility of controlling the abiotic factors as here.
We hope this launch of "Ground Seeds" will not be sterile
