For this KEU 280 (Project 1). our project is design the Smart Horne System. This smart home system gives much more benefit to us. F-’or this big title are divided to ten sub topics which is alarm sensor, automatic cotton for window, heat sensor, infrared motion detector and etc.
In this project, we choose to build a full duplex intercom.system that is important to this smart home system. The intercom system can called intercommunication system. This system can be defined as an audio frequency amplifier system that provides two way voice communications between two or more location, which are using high frequency and in the same structure.
In this thesis, we design a full duplex intercom system that is containing two stations. Each station contains a dynamic loudspeaker that also serves as microphone. The amplifier can be at station or each station may have its own amplifier. Connection between stations can be made by wire or carrier signals traveling over electric wiring in the building. It also widely used on ships and large air craft. In other words, an option on many business phone systems which allows us to use an abbreviated dialing sequence to react another telephone connected to the same communication system and it also called duplex intercom
