A low cost smart energy monitoring and control system for smart buildings

摘要

With the global energy demand to rise significantly in future, the onus is to reduce energy wastage by employing real-time energy-consumption monitoring and control. In this work, an energy consumption measuring plug is designed and developed which monitors and controls energy usage of appliances in real-time. The design itself is based on low-cost, commercially available hardware such as ADE7753 energy meter IC, ATmega8 microcontroller, current sensor, etc. The monitoring system developed has shown low average error rate of 0.66 % in power measurement when compared to commercially deployed energy meters, hence proving its accuracy. The analysis of individual feedback on energy usage based on these smart monitors is being carried out as part of a five weeks field trial. In these five weeks of trial, the proposed system has led to about 12% reduction in average power consumption when compared with legacy systems that do not involve smart monitoring systems.
