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
you are right.But in my project I don't need to these advantages. So, I'll see.
thanks sir
Take a microcontroller you have available. Or that you have knowledge about. Or that you have access to tools for. It doesn't matter which you take. Any talk about "best" is just a big fail.
Thanks Mr.Per Westermark. I think I'll use 8051,I started learning how to program it. I'll try to finish it.
thanks
Ok sir..What do you think?? I'll use SIM900 GSM module.
