Abstract
One implementation of the Internet of Things (IoT) conducted in this study to realize the system of monitoring and control of electrical energy usage-based Wireless Sensor Network (WSN). This research method is the design of wireless sensor nodes that can measure the electrical parameters of alternating current (AC) as effective voltage, effective current, active power, apparent power, power factor and total electrical energy consumption by using modules ESP8266 as a liaison with a Wi-Fi. Calculation of electrical parameters obtained from ATmega328P microcontroller ADC readings of a step-down transformer that is used as a voltage sensor and sensor SCT013 used as AC current sensors will be transmitted to the server over the network from a Wi-Fi Access Point (AP). ESP8266 modules are programmed using AT-Command proven to reliably measure can transmit data simultaneously with serial data format of the wireless sensor node to a server using TCP / IP protocol. Monitoring power consumption via the internet which are designed in the research, either through the Android application and web browser proven to be reliably able to show some electrical parameters with the same data than the data logger recaps taken from SD-Card installed in the wireless sensor node.

Summary
Dalam pemanfaatannya terkadang tidak diketahui berapa banyak energi yang sudah terpakai sehingga cenderung terjadi pemborosan energi lisrik, sehingga perlu dilakukan pengukuran penggunaan energi listrik tersebut.[1] Perkembangan teknologi internet saat ini bukan saja hanya menghubungkan orang, namun menghubungkan orang dengan benda, dan juga benda dengan benda. Hal ini dikenal dengan Internet of Things (IoT) yang dapat dipahami sebagai lapisan informasi digital yang mencakup dunia fisik yang memungkinkan berbagai perangkat untuk saling berkomunikasi satu sama lain.[2] Wireless Sensor Network (WSN) merupakan salah satu bagian implementasi dari IoT yang terdiri dari kumpulan node sensor yang tersebar di suatu area tertentu. Dari perkembangan teknologi Internet of Things yang sudah mulai memasyarakat saat ini, muncul pemikiran untuk mengintegrasikan beberapa sistem sensor tegangan dan arus listrik bolak-balik (AC) yang terhubung secara nirkabel melalui suatu jaringan Wi-Fi untuk memonitor penggunaan energi listrik secara on-line melalui internet web browser maupun aplikasi Android. Metode penelitian yang digunakan adalah rancang bangun wireless node sensor dengan menggunakan modul ESP8266 sebagai penghubung dengan server melalui jaringan Wi-Fi yang tersedia
