Can I do this project? Reed switch + 8051 + GSM module??

[mohammed]

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

The project is possible, no doubt!

[mohammed]

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

[AJISH ALFRED]

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.

hey mohammed u completed that project..i wanted some information about reed switches.how u connected reed switches to microcontroller?can we directly interface reed switch with MCU?

dear sir ajish!

                i have problem ,how get data from MCU UNIT  trough sending sms…..and how to switch on and off GSM SIM900 MODULE  by sending sms….plz sir reply must … i need it urgent

                         thanks

basic commands to check the gsm modem working properly or not  follow the commands 

at        pres enter

at+cmgf=1    press enter

at+cmgs=”your mobile number”    press enter

-> type your message to your reciever end people

finally press (control +z) 

 

 

[umar farrok]

try that code in your hyper terminal window after connecting your gsm module with sim

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
