Development of prototype and measurement, control and automation system in real time for small production greenhouses

Abstract

The main objective of this work is to develop a real-time control system and accessible instrumentation for small production greenhouses located in the State of Guanajuato; whose goal is to increase production, make optimal use of the irrigation system and efficient water management. For this, a prototype of a greenhouse irrigation system was built with the inclusion of temperature sensors, environmental relative humidity, flowmeters, solenoid solenoid valves and soil humidity sensors, these values are compared with a numerical model to corroborate the magnitudes obtained and assess the delivery of flow and irrigation time in each section of the laboratory greenhouse. The development of a graphical interface in LabVIEW for the control and operation of sensors and the complete irrigation system stands out, being this quite intuitive and easy to use for a farmer. The results obtained from the work show differences between the measured and modeled of the hydrodynamic variables in a range of 8 to 10%, where it is concluded in an improvement in the development of the code in Arduino for its optimization in response time and migration to mobile platforms.
