Smart electrical appliances controller using SMS

This article is about a simple low cost, small sized controller that helps people controlling their home appliances remotely even if they are outside their properties. The system lets them turn on or off any device while being outside home by sending messages using mobile phones. Moreover, a message could be sent to know more specific details like the temperature of the boiler, AC, etc. The main purpose of this system is to adapt with the private electricity subscription issue that almost all the Lebanese citizens are using to cope with the long electricity current cut off periods. However, the difference in payment rates between the normal current and that of the subscriber is always making a big concern over electricity consumption. Hence, the system will help users to minimize their payments for electricity usage by informing them if the current is on or off so they can control their appliances accordingly.
