RT Journal Article T1 Easy Handling of Sensors and Actuators over TCP/IP Networks by Open Source Hardware/Software A1 Mejías Borrero, Andrés Manuel A1 Sánchez Herrera, María Reyes A1 Márquez Sánchez, Marco Antonio A1 Calderon Godoy, Antonio José A1 González, Isaías A1 Andújar Márquez, José Manuel AB There are several specific solutions for accessing sensors and actuators present in anyprocess or system through a TCP/IP network, either local or a wide area type like the Internet.The usage of sensors and actuators of different nature and diverse interfaces (SPI, I2C, analogue, etc.)makes access to them from a network in a homogeneous and secure way more complex. A framework,including both software and hardware resources, is necessary to simplify and unify networked accessto these devices. In this paper, a set of open-source software tools, specifically designed to cover thedifferent issues concerning the access to sensors and actuators, and two proposed low-cost hardwarearchitectures to operate with the abovementioned software tools are presented. They allow integratedand easy access to local or remote sensors and actuators. The software tools, integrated in the freeauthoring tool Easy Java and Javascript Simulations (EJS) solve the interaction issues between thesubsystem that integrates sensors and actuators into the network, called convergence subsystem in thispaper, and the Human Machine Interface (HMI)—this one designed using the intuitive graphicalsystem of EJS—located on the user’s computer. The proposed hardware architectures and softwaretools are described and experimental implementations with the proposed tools are presented.
