Diseño e implementación de un prototipo de monitoreo inalámbrico de temperatura, energía y módulo de entradas/salidas con almacenamiento en la nube para la empresa GENTEC S.A.

Abstract

The main objective of this research project is to design and implement a prototype for wireless monitoring of temperature, energy and input / output module with cloud storage for the company GENTEC S.A. In this project is developed a pattern of a sensor network consisting of an electrical energy sensing module, which acquires the data of a commercial meter through MODBUS RTU on RS-485 and a reading module with four digital inputs and operation of four relay-type digital outputs. All these modules communicate wirelessly using Zigbee technology with a coordinator module responsible for collecting the data of each module, which is composed of a single-board computer (Raspberry Pi 3B +) and a 3G modem that allows us to send the collected information towards a cloud application developed in Node-RED where it is stored and analyzed. It is important to emphasize that the prototype was developed based on the requirements of the sponsoring company, in addition to the fact that each module is installed in the offices of GENTEC S.A. where the prototype performance tests were performed.
