Industrial Automation is a field that requires a vast involvement in the safety and the security aspects. The intensity towards this concept may vary according to the nature of the industry. The security feature must be more intense as compared to less complicated industrial plants [1]. Here we are proposing an idea that well suits the kind of industries formerly mentioned. The system is designed to handling the electronic devices (230V AC to 500v AC) and monitor two very important parameters – the fire detection and gas leakage detection. For this we are using basic Xbee module, Pic16f877 Microcontroller (MC), 1pole relays, gas leaking and fire detecting sensors. The Xbee modules provide the communication mechanism between the user module and server module by means if messages. xbee modules provides wireless communication so we have to provide security to the messages by using two mechanism’s. One mechanism is encrypt the messages by using TEA Algorithm, another mechanism is changing the baud rate. Micro Controller will be responsible for handling the electronic devices and sending messages to the Xbee modules and EMBEDDED C programming to handle Micro Controller. The behavior of the system can examined experimentally.
