Internet of Things (IOT), a concept which aims to extend the benefits of Internet connectivity are connected continuously. Today, with the development of technology is very rapid, communication tools is very important and very necessary control equipment to control the electrical load. Tools microcontroller-based monitoring and control has resulted in many highly developed method. At this time the communication is not only used for communication among humans alone, but between man and control tools through the Internet or now better known as the Internet of Things. The use of transformers step down as sensor AC mains voltage and current transformers SCT013 as AC current sensors with schematics and use of components and algorithms appropriate programming for microcontroller programming ATmega328P can be determined accurately parameters AC power as effective current, effective voltage, apparent power , active power, power factor and akumulai use of electrical energy at a certain time, so that the electrical parameter data can be monitored remotely by means of wireless communication. ESP8266 modules are programmed using AT-Command proven reliable can transmit data that consists of several electrical parameters simultaneously with serial data format of a sensor node to a server using the TCP / IP network using Wi-Fi is available. Monitoring power usage through the internet with web browser Android applications and 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. In addition to monitoring, the electric load also can be controlled remotely via the Android-based applications by leveraging server that can be used freely for the development of the Internet of Things technology in Indonesia.
