GSM Car alarm system

I had had a problem like you.
I have sold them with a GSM phone ERICSSONA A1018s. I opened the keyboard and conect contacs vith MCU (in my case DAQ NI USB6008). Then I have wrote (drawn) the software with LabView and it worked then.

Re: GSM Car alarm system

Its pretty simple thing, but tell me which controller and modem are you using for your project other than your mobile phone. When u say how to activate the system what do u mean and it involves both hardware and software and AT command interaction between modem and controller and your phone.

Please let me know what is your doubt clearly as u may not have much time in graduation project.

Hi,
If the mocro processor is interfaced to car alarm system and the GSM phone, it can interpret a receved SMS as a command to turn on the alarm system.
