IoT based electrical energy monitoring system.

Electrical energy is one of the most important things today, therefore, to find out whether the energy obtained by consumers can be utilized properly, the electrical energy monitoring system was created to be able to carry out monitoring remotely. In the study using the ZMPT101B voltage sensor, ACS712 current sensor, current transformer and Powermeter Schneider 5350, then ZMPT101B voltage sensor and ACS712 current sensor are integrated with Robotdyn Arduino which is connected with Arduino Ethernet Shield, than for current transformer integrated with Powermeter 5350 which is connected with the Schenider Programmable Logic Controller (PLC) TWDLC40AEDRF. The results of reading data from Robotdyn Arduino and Programmable Logic Controller (PLC) Schenider TWDLC40AEDRF are then sent to the Mysql database via an Ethernet network using the KepserverEx application, the data that already exists in the Mysql database is then displayed on the website te which has been created using PHP files and Bootstrap Framework. The test results of voltage and current measurements using the ACS712 current sensor and ZMPT101B voltage sensor obtained good results, the results of measurements of active power measurement, apparent power, reactive power, power factor, and frequency of current transformer and Powermeter 5350 obtained good results, with error percentage less than 5%, website access can be done well and the database connection is successful without data defects.
