Multi-Sensor Embedded System with Multiple Communications Based on EDU-CIAA

Abstract

The argentinian CIAA project carries out the development and production of embedded systems, for educational, industrial and scientific purposes. The present work consists in designing a comprehensive embedded system based on the EDU-CIAA NXP version, for educational and applied research purposes. The hardware and software are developed in order to provide a shield of Internet of Things (IoT), providing multiple technologies such as: wifi, bluetooth, GSM, SD portability, and RF. A practical application is developed for sensing and monitoring multiple agricultural variables remotely. The development has two main parts. The first is based on an ATMEL microcontroller and it consists of the use of sensors nodes and communication modules. In the second part, a central node with processing capability is designed. For specifications, the national development platform EDU-CIAA NXP and the designed IoT expansion board are used in the second stage. The development has an HMI interface for Smartphones and PCs, using an Android App and web server. All software and hardware developed are shared in an open repository on GitHub.
