Lab VIEW based Wireless Notice Board

Notice Board is primary thing in any organization and institution places such as schools, colleges, and public utilities such as shops, offices and other places. This wireless board can be used to save the environment from places where more papers, ink, and other organic material and especially a great time saver rather than posting a notice board with man power. ZigBee is a PAN technology based on the IEEE standard. Unlike Bluetooth or wireless USB devices, ZigBee devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one to another device. This technique allows the short range of an individual node to be expanded and multiplied, covering a much larger area. The information is transmitted using ZigBee technique. The project is built around the pic micro controller. This micro controller provides all the functionality of the display and wireless control. It also takes care of creating different display effects for given text. The LabVIEW is also used as a graphical user interface in this system. LabVIEW is a highly productive development environment for creating custom applications that associate with real-world data or signals in fields such as science and engineering. The message can be transmitted to multi point receivers. At any time, the user can add or remove or alter the text according to his requirement. There is also user authentication in system used to avoid order to avoid any misuse in the system
