Experimental scope of an electrical energy consumption device based on multi-microprocessors, local printed circuit boards and Internet of Things (IoT)

Abstract

Faced with the need to implement applicable policies for the assurance of the quality, many consulting providers choose to import power quality and energy analyzers, since in Honduras there is not an infrastructure for the production of electronic devices. This work presents experimental results of an alternative based on the interconnection of different local accessible microprocessors through Serial Peripheral Interface links, electronic boards designed in freeware to adapt and measure effective voltage signals up to 240 Vrms, effective current signals up to 40 Arms using both rigid and flexible clamps, temperature and relative humidity for considerations of environmental conditions and communication by Wi-Fi using a Java interface, adjustment option according to a calibration certificate issued by an accredited laboratory, all in a portable equipment to be able to carry out studies with a device that is supported national technician.
