Control of electrical devices by a wireless system

Keywords: Wireless communication, RF, Microcontroller, Computer Controlled The aim of this thesis working is to improve employability and installation convenience of a system designing a equivalent wireless system instead of old wired system and to design a new electronic circuit of this wireless system A few ICs which come from various producers are tested and chosen the one which has the best efficiency, higher ease of use and lower price to reach the aim of the thesis. Designed circuit is controlled with a higher level software that is embedded inside a microcontroller in this way a wireless system is designed equivalent security with wired system. Some external devices are designed considering whole system malfunctions.The system security is improved with this way. At this point the new wireless system has more advantages than wired system. These are high level ease of use and installation convenience.
