Sistema de monitoreo de condiciones climáticas en un invernadero de rosas

Ecuador is one of the countries that is among the leading exporters of roses in the world, however, in many greenhouses that are dedicated to this activity does not have adequate control of all climatic conditions necessary for the proper development of roses. The objective of this study was to develop a low-cost climate monitoring system, which would collect all the necessary information about 3 previously identified zones. By using various sensors such as DHT22 which collected humidity and temperature, MG811 carbon dioxide sensor and hygrometer sensors to measure soil moisture. It was obtained that in the first zone, the temperature that was most obtained was 19.4°C, an arithmetic mean of 19.39 °C, a standard deviation of 0.39 and a low variance of 0.154 °C. With respect to the Humidity of the environment of the zone 1 the following values were obtained: the value that was most obtained was of 77.6 %, an arithmetic average of 80.10% and a variance of 30.40 %. With respect to zone 2 the following values were obtained: the temperature that more was obtained was 19.2 °C, an arithmetic mean of 19.43 °C, a standard deviation of 0.41 and a low variance of 0.165 °C, with respect to the humidity of the environment the value that was most obtained was 99.9%, an arithmetic mean of 98.56%, a standard deviation of 1.96 and a variance of 3.835 %. Finally, for zone 3 the results were the following: the temperature that was most obtained was 19.5 °C, an arithmetic mean of 19.37 °C, a standard deviation of 0.39 and a variance of 0.154 °C, with respect to the humidity of the environment, wasobtained as the most repeated value 91.4%, an arithmetic mean of 88.18 %, a standard deviation of 4.12 and a variance of 16.956%. In relation to the soil humidity by zones, the results obtained were the following: in zone 1 the soil humidity was 93 %, an arithmetic mean of 93.22%, a standard deviation of 0.58 and a variance of 0.332%. In zone 2 the value of humidity of the soil that was most obtained was 95 %, an arithmetic mean of 95.19%, a standard deviation of 1.30 and a variance of 1.682% and finally for zone 3 the value of humidity that was most obtained was: 98%, a standard deviation of 1.93 and a variance of 3.719%. All the temperature parameters are within the ideal ranges for the correct development of the roses, the soil and air humidity were close to the optimal ranges because according to what was observed in the greenhouse, the roses were developed correctly, thus verifying the proper functioning of the implemented prototype.
