Resumen
In this paper we describe the development of a system, which allows the control of the physical variables humidity, temperature, and monitoring of CO2, in order to carry out different demonstrative practices that allow to strengthen the knowledge in the area of Control and instrumentation. For the use of a PLC, the PLC is also in charge of controlling the temperature and humidity through a PID and an on / off control; In turn, as a complement, the use of a PC and an Arduino that serve the slaves of the MODBUS red, which allow to modify the data of the control and to monitor the physical variables and those mentioned, also use a PSOC card that allow the Acquisition of temperature and humidity so that the PLC can process them. As a result, a device capable of controlling the physical variables of temperature, humidity and CO2 monitoring was obtained through local (PC, LCD, Keyboard) and remote (Android Application) visualization.
