Development of embedded system for making plugs smart

Smart Switch allows switching almost any appliance ON and OFF remotely via local network or via internet. Such switches are designed to receive start / stop commands and to monitor smart switch applications such as voltage, current, and power. The study presents a smart power switch system that can be controlled wirelessly or via internet, which has ability control power outlet and monitor electrical events such as voltage, current and power consumption. This system embeds program into microcontroller to control over all process, in addition to voltage and current sensor. The main system features include the remote control of multiple power outlet, control smart plugs, real-time monitoring of the current, voltage and power consumption. Also, it schedules the devices on/off time with consumption limits, calculate the electrical cost that user can interface it by any operating system. A prototype of the system has been implemented and tested with local network and internet in order to monitor its functionalities. The overall results proved that system runs fast and has very close energy monitoring to common monitoring devised. This system can be replaced manual distribution board and old energy meter to have one auto-remoted real time monitoring smart switch. Keywords: smart switch, smart home, power switch, power meter.
