Introduction A Notice Board is a place where people can leave public messages. Notice boards are often made of a material such as cork.

Problems with Wooden notice board:

Problems with Wooden notice board Manual display of message Multiple people struggle and cluster a single wooden notice board for information just released, e.g. Exam results. People mutilate, remove or destroy paper notices from the notice board leaving other people to be uninformed. There is unregulated display of information, difficulty in storage and no efficient reference to past relevant information being posted.

Solution :

Solution Digital signage is a form of electronic display that shows information, advertising and other messages. Development of a Digital Notice Board (DNB) program, which can be installed on various computers connected together by local area network (LAN) so as to increase the rate at which relevant information is being disseminated to the public within a certain location.

Major Problem Associated with Digital Signage & DNB:

Major Problem Associated with Digital Signage & DNB Digital Displays are most usually controlled by basic Personal Computers by way of proprietary software programs involving large capital outlays for the controller equipment. N o mobility for transmitter.


Solution The solution to the problem of mobility of transmitter can be solved by making the transmitter wireless and mobile. For this purpose we are using a mobile transmitter and a wireless modem as a receiver. This setup is entitled as “SMS BASED NOTICE BOARD”. At this time we are focusing on the implementation of this setup specially for colleges.


Advantages If there is some urgent notice to be displayed on the notice board there is no need to go to the notice board. The management can simply send the SMS to Electronics notice board to display the notice. It is very time saving for the management.
