Hi
I want to build a system contain sensor ,Microcontroller and GSM module. I'll use SIM900 GSM module. The main idea of this project if Reed switch sensor connected I want the GSM module send an alarm message to a mobile.
Can you help how I can do this?? some steps and hints. For GSM module I read about AT commands and I knew I must desire if I want it receiver or sender.
Any suggestions it's will be better. Thank you
In fact I'm confused now! which one I'll choose?? PIC,AVR or 8051 ?! My application is simple, so I think I can choose 8051 ?? I don't need to choose the best one ! ( I think that )..
What do you think??
On what basis did you initially choose the 8051 at (or before) you started this thread?
Certainly, nothing you've said so far is in any way beyond the reach of an 8051
