    Nowadaysindustrial applications are built on automatic control systems. The main reasonis to convert these control systems and industrial factories into smart ones.By converting them to smart factories, a high efficiency rate can be acquired.Generally automatic control systems are controlled by classical logic via PLC(Programmable Logic Controllers). In this method many problems can be met with.The most important one of these is that it is very difficult to create amathematical control unit. Trying to control the system with the traditionalway without creating a model can lead us to complicated algorithms. At the sametime complicated algorithms can cause wrong orientations in the system. Howeverthe fuzzy logic, which is one of the smart control methods, can help us tocreate the system just with linguistic expressions and some rules withoutrequiring a mathematical model. In this way with smart control methods,efficiency can be obtained in factories. Besides control systems, factories canbe made smart. The RFID technology is the main element of this process. Thefactory-material communication is provided via RFID technology. Thus, factoriescan communicate with the material that is produced without any humanintervention. The development of the smart factories and the rapid improvementsin automation systems caused demands in wireless technology to rise. As aresult of these demands, wireless sensor networks became a very importantsubject and its use is widespread. These systems provide us to send the data ina certain distance without any loss of the data, also removes all the cables inthe workplace. In this study a control system, distributed in wireless sensornetwork based industrial places, is controlled by a traditional PLC method andfuzzy logic. At the same time, the system is monitored by RFID and a solutionis proposed to a smart factory application.
