GSM Based E-Notice Board

Abstract

The concept of a wireless digital notice board using GSM technology has been introduced in this suggested system. Therefore, cutting down on time and paperwork is our primary goal. In order to show messages sent to the GSM module on the notice board by authorized users, we are attempting to implement our system in this article. To put it briefly, the GSM module at the digital notice board receives the message from the authorized user and displays it on the notice board at a remote location. At the same time, the message is delivered to various user mobile numbers that are saved in the microcontroller memory. Therefore, essential messages or notices will be sent to the appropriate mobile numbers in a very short amount of time. This indicates that a user or registered individual can send a message from any location, and the message will be shown on an LCD display.
