| Summary: | Smart plug technology currently for user providing one plug module that is able to monitor and control the state of electrical appliance. The addition of plug number gives some deficiencies such as from cost point of view. By looking at the disadvantage made the tool which is able to monitor and control electrical appliance so that smart plug more than one integrated plug module. The manufacture of plug modules includes system design, sensor type selection in module, data delivery process, comparison of measurement module with measuring instrument and system test. From the results of the design is known that the module can perform data transmission, display the monitoring page and do the control and obtained percent accuracy of current readings obtained between 91.50% to 99.61% and the percent accuracy of the voltage readings obtained are ranged between 98.95% to 99.90%.
