Automated Electronic System to Prevent Freezing Damage to Crops IEEE EDS - SIGHT / Stage 1

Abstract

The present work shows the design and implementation of a prototype capable of mitigating the damage in pastures produced by the so-called "frost"; To start the development of this prototype, a description of the types of frosts existing in the country is given, showing which one has the greatest incidence in the Cundiboyacense region and which phenomenon affects crops and/or pastures.

The development is carried out in the following way, instrumentation stage in charge of measuring the temperature and humidity present in the environment, important variables which allow knowing when the frost phenomenon is going to occur, for this reason the investigation of physical variables that can predict the existence of frost, taking into account that it is a type of freezing in crops, the temperature variable is studied and in what critical conditions it begins to affect pastures, in addition, investigations are carried out of % relative humidity, it is also explained why humidity must be taken into account as a variable that predicts a frost. In addition, the content contains an explanation of the selection of the control method responsible for creating a microclimate around the plantation and/or selected area. As a final stage, the results of the design of the energization system using photovoltaic cells can be visualized.

Finally, a mobile App is built which allows the acquisition of data through communication between the bluetooth module and the Arduino programmable card in order to know the data of the added sensors.
