Wireless Electronic Notice Board using GSM




This project demonstrates how to design a wireless electronic notice board using SST89E516RD-40-C-PIE microcontroller. The notice boards are important in public places like railway stations, parks and airports. Presently almost all electronic notice boards are designed using wired system. One of the drawbacks of the design is the system’s flexibility in terms of placement. The aim of this project is to develop a wireless notice board that can be installed in any public areas and will display the latest information sent from the user’s mobile.

Wireless Electronic Notice Board using GSMThe above circuit consists of Microchip Technology’s SST89E516RD-40-C-PIE microcontroller, GSM module, level converter and 16×2 LCD. The LCD is connected to P1.0 and it is used to display message. The GSM module is connected to the SST89E516RD-40-C-PIE microcontroller through the MAX232 IC. Only four data lines are required to display the data, which are connected to P1.4, P1.5, P1.6 and P1.7 respectively. In order to communicate with GSM, some AT commands are sent through the serial connection (UART Protocol). The module requires 9600-baud rate. The GSM modem is duly interfaced through level shifter IC for establishing RS232 communication protocol to the microcontroller. The message received is sent to the microcontroller that further displays it on electronic notice board, which is equipped with a LCD display. It is interfaced to a microcontroller from 8051 family duly powered by a regulated power supply.
