In this Paper a new kind of system is proposed to make an RFID Based Electrical Supervisor This technology implemented successfully in all over the world. But in our area it is not so improve. So using this technology here we made an attempt to implement RFID based electrical supervisor. In this project, we are using RFID technology for monitor and control electricity used in one room of hotels, companies through RFID transmitter, receiver and Microcontroller. The use of RFID technology is a key aspect to control the wastage of electricity used in hotels, companies, etc. This project presents the idea about progressive radio frequency identification (RFID) technology for Electricity control. In this project, we are using the RFID technology for measuring and monitoring load of electricity and Microcontroller which is 89C51 will process the data in which the controller will be maintained.
