ZigBee and RFID based monitoring, protection and security system is proposed in this paper. The smart node used in this system measures parameters like power, current, voltage and temperature. To prevent electrical fires and overloading, a threshold value is set at each outlet. The power and temperature parameters assessed by the smart node are transmitted to the base node through ZigBee. If the temperature exceeds or an overload occurs, a set of remote control instructions are executed in the PC. The base node instructs the smart node to cut off the power to the corresponding branch circuit. The entire operation can be monitored from a remote station. In this proposed system, RFID technique is added to provide a theft control mechanism. To prevent theft of valuables from an unauthorized person, RFID tags are used. RFID reader senses the RFID labels (master/slave tags) continuously and sends the information to a PC through ZigBee protocol. The database is checked in PC with the received information. If there is any mismatch in the RFID tags, it is considered to be an illegal input and a warning message is generated at the PC. The database is checked for the owner of that particular item and a confirming message is send to that owner. To search for that item the owner can login WEB. The valuable will be stopped by the entrance guard.
