Information display system proposed in this paper is an efficient, wireless and smart mode of communication in public places. Public announcement system, programmable sign boards, notices in hard copy form, etc are hardwired, complex in nature, requires manpower and have some time-delay. All these limitations are overcome by the proposed model. This paper describes an advanced notice board that can be operated with GSM technology or with a PC with an administrator. It is GSM based that displays information upon receiving SMS from an authorized user. Use of GSM technology for communication enables the remote operation. The LED board can also be connected to a PC, to display the message. This work is done by designing and integrating the hardware and software with a microcontroller, GSM module, PIR sensor, and a LED display.
