 Motivation
• Visibility from maximum area
• GSM technology aims in reducing the complexity
• for sending a message by incorporating SMS technology.
• This technology can be used in public areas such as hospitals,
schools, multiplexes and buildings
• to improve the security system ,
• to spread awareness in an emergency.

 Objectives

 To display the message on display board through SMS.

 To effectively receive and transmit data via SMS.
 To eliminate the need of being physically present
 to hangout the paper notices.

 To provide reliable, authenticated, user friendly display system.

 Scope of Project
• Used in government offices even on the off-days
• as data can be transmitted from anywhere.
• It can be used in daily population projection.
• It can be used to show emergency warning.
• It can be used in roadways to show direction.

03/07/2021 5
 Project Applications
• No need of any difficult wires
• to display the information on the LCD as
• it is wireless.
• Easy to operate and Consumes less power.
• This circuit is handy.
• To display the information wirelessly in public areas like
• bus stations, parks, railway stations, colleges and organizations etc.

 Working Principle
• Initialize the LCD and UART protocol
• Check for the command +CMTI: “SM”,3 (Location number) to
know whether the new message is received or not.
• If you receive the command, then store message location
number.
• Now read that particular location and extract the body of the
message.
• Display the message on LCD

03/07/2021 12
 Result
• Character seen in LCD display
• by entering the updated information

03/07/2021 13
 Analysis/Discussion of Results

• The project helps for display message

• Can be extended to use in different fields
• Difficulty on deleting data show on screen
• Adding Memory
• Hardware component are not available

03/07/2021 14
 Future Enhancement
• A commercial model can be able to display more than one messages
at time.

• LED display can be used instead of LCD display.

• Automatic text to voice system can be made
