Environmental variables monitoring system and irrigation control in a greenhouse (RIO)

Abstract

The waste of water in recent years in the world has been increasing drastically, such is the case of the irrigation systems of the different crops that exist in addition to the multiple conditions where they are operating either in the open field or in a greenhouse. 70% of the water used in Mexico is destined for agriculture where 60% of this destined water is wasted by irrigation systems either by infiltration or evaporation. In Guanajuato the construction of greenhouses throughout the state is very common with different crops. The main objective of the project is to reduce the consumption of water in the irrigation systems, as well as to reduce their operating costs. To achieve the goal, an embedded system will be developed using microcontrollers, which will measure the greenhouse temperature at different points and through radio frequencies, a multipoint network will be created implementing xbee modules where the temperatures obtained will be sent to a central device which will process the information and activate irrigation automatically. To achieve this, techniques such as serial communication, analog-digital conversion, multiplexing, data analysis will be used.
