    Hi every buddy.

    I want build this project, first I wanna make sure can I do it or no??.
    My project is Wireless Alarm System,I`ll use reed switch with 8051 Microcontroller and GSM module exactly Arduino SIM900.
    I want if the switch connected gsm module send a message (that I created and wrote it in gsm module) to a mobile.

    Thanks..I wait you all

    what do you think,about better GSM module to use??

     

    And, Can you give hints about C code??

     

    thanks sir

    SIM 300 is a widely used module. You should learn AT commands to control the module before start coding. 

    Try making call, sending message etc. by sending AT commands through hyperterminal to the module. If it works, then your code running on the microcontroller should be capable of sending the same commands serially to the module. 

    Feel free to ask more doubts. Good luck with your project.

    Hi

    I started my project, but I`ve an question, Can do it without screen??
    because I don`t need it.

    Another question. What about MAX232 component?? is it important??

    thanks

    Hi Mohammed,

    Screen, well its upto you.

    MAX232 is basically a serial to ttl converter. Your controller can read only ttl logic. If your GSM module is communicating with RS232 serial standard, you need a RS232 to ttl converter. MAX232 will do this job.

    If you share your circuit shcematic and details, we could help you more.

    thanks frooq!

                         i already use these command…but now i want to control it by myself…means that when i want to get data ..simply i send sms to MCU unit  through gsm module and get data…and turn it off OR on sleeping mode….dear friend Is it possible????

                                                          plz reply me quick..thanks
