GSM Notice Board




This project is a simple GSM Based project where 20x4 LCD is used as display for Notice board and GSM modem is used for receiving and sending SMS. When a user wants to display a notice/message on the notice board, user will send sms from a verified mobile number and sms recevied is displayed on LCD. Project involves simple security feature where SMS sender's number is compared with a pre-configured number (hardcoded in source code). If sms is recevied from an unknown sender, a notification SMS is sent to pre-configured number notifying an invalid access to board.

This project is fairly simple but its main purpose is to demonstrates reading and sending SMS using GSM Modem. There are many users on forum who struggles getting SMS read working in their projects. So For them this project is a starting point.

I want to thank Kiran Gowle (kirangowle) for submitting this project. I am sure his contribution will help many others on this website. If you have any queries regarding this project, Please feel free to post in forum.

@siddardha, it should work with any modem as SMS commands are as per GSM standard. In this project I think SIM900 is used.

@siddardha, You will need a real modem which connects to your PC serial port. and in proteus instead of using virtual terminal use COMPIM component which uses your PC serial port so you can talk to real world devices. If you need more help please post in forum.

Can i use this code for 16 X 2 LCD ????
I used AT89S52 controller... & SIM 300 GSM module...

11 Feb 2015: 04:47 AM
This code uses 4 line LCD so addresses of line will change, you need to change it to use 2 line LCD.

@masharif46, I suggest you post in forum for any further question. At first look at the GPRS shield. It does have TTL connections. and even the wiki page says the same:
"The shield also has the 12 GPIOs, 2 PWMs and an ADC of the SIM900 module(They are all 2V8 logic) present onboard." Please if you have anymore question, post in forum.
