Elton Nobre Morais, Pedro Hericson M. Araújo, Leonardo Da Silva Costa . IoT System with Access Control Integrating RFID and Non-invasive Air Conditioning. International Journal of Computer Applications. 178, 52 ( Sep 2019), 5-11. DOI=10.5120/ijca2019919378
This article describes the tools and technologies used to manage an integrated system consisting of RFID access control and noninvasive infrared air conditioning. In this sense, was developed an IoT (Internet of Things) platform consisting of hardware – responsible for controlling the access of users through the recognition of an individual RFID tag, as well as the capture and transmission of infrared signals – and software – a Web system for monitoring and remote control. Was also developed web software to monitor access and register new users and environments, where it is possible to define user profiles besides the registration of activities in each site. As resources are usually limited in IoT systems, it is necessary to use application protocols that optimize the transmission between sensor nodes and gateways, as a result of this the Message Queue Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP) protocols were used for communication between the RFID access control system (RACS), infrared air conditioning control (IACC) and the Web system. The proposed platform was tested and validated in a classroom.
