Friendly home automation system using cell phone and J2ME with feedback instant voice messages

This paper introduces a friendly system to control the home appliances remotely by the use of mobile cell phones; this system is well known as "Home Automation System" (HAS). The designed system covers the most important required factors in home automation system such as flexibility, security, easy to use, the ability to feedback information to the client immediately,... etc. The presented system uses the J2ME language to program the client mobile which sends information to the service mobile and this controls the operation of the appliances via a PIC microcontroller which connected to it and programmed in such a way that introduces the main characteristics of the system. Optocoupler and static power switch (TRAIC) are used as the interface devices between the PIC and the home appliances. The proposed HAS in this paper is implemented practically, tested and gave the correct and expected results.
