The system can be implemented in the Plant Monitoring System. It consists of a Coordinator and the sensor nodes. The coordinator is a centralized unit which is attached to the monitoring PC through TCP/IP network. It collects the information from all other nodes on demand and provides to the end user through TCP/IP network. The sensor nodes are made intelligent for controlling the plant. These nodes are attached with the Zigbee for remote controlling in case of changing the preset values and handling any issues. The experimental results obtained demonstrate the usefulness of the proposed system in terms of the low power consumption, low cost, targeted towards automation and remote control applications.The coordinator is implemented using the ARM9 controller and the Sensor Nodes are implemented using the ARM7 microcontroller. RT-Linux is used at the coordinator for real time operations and the Sensor nodes are programmed using the Embedded C.
