Internet of things (IoT) is widely used in engineering as an environmental and smart cities monitoring, among others. This study develops a monitoring system and a remote control for a pressure regulator valve through an IoT communication tool. MatLab® and HTML Programming platforms were used. The development system for access and communication is based on Arduino Mega and Ethernet Shield respectively. This system allows to control the reference pressure regulator and to monitor plant transducers information. Among the advantages of such developments are the availability of a free server and a low cost development system; besides, these projects lead to improve infrastructure of laboratories equipment in the engineering field, so they may be remotely handled.
