Data acquisition and measurement unit based on Wi-Fi communication protocol

Abstract

Without a doubt, the accelerated pace of competitiveness in industries is one of the main factors that cause the rapid evolution and growth of electronic and communications technologies. The growing need to develop new products with the best quality, quickly and more economically, as well as to ensure and increase the competitiveness of these products in international markets, requires new technologies for the measurement, monitoring and control of their production processes, whose purpose is to improve the processes to ensure their products are present in the market in the shortest possible time, with the highest quality and low cost for the final consumer.

This work is based on the design and implementation of a system for data acquisition through WiFi wireless communication, which is mainly directed, but not limited to, the measurement, monitoring and control of production processes in industry, commercial and home measurement and automation applications, making use of one of the wireless communication protocols with the greatest acceptance and presence in the market, with which it is intended to take advantage of the physical infrastructure installed in terms of communications at the place of application, be it home, business or industry.

The Unit is based on the Roving Networks RN-131G wireless communications module, which is enabled to work in local mode with very low power consumption supporting WiFi wireless protocol with transfer speeds of up to 54 Mbps, through which it is possible to acquire or measure up to 5 analog variables with 14-bit resolution and includes a temperature and relative humidity sensor, measure two digital signals and act through two digital outputs, all of them conditioned in 0-5v and includes a USB port for communication and/or programming.
