gsm alarm

Hi guys,

Not going to ask anything too deep, just need a yes or no.

Can I use one of these:

**broken link removed**

OR

**broken link removed**

To recieve a command from a (not decided yet) PIC which amounts to an SMS message which can be recieved by a single dedicated number?

Thanks
 

gsm alarm source code

Yes. You can use either of them.
 

Yes,

Just going to share a bit more for the benefit of other member

1. get a microprocessor with UART
2. learn about AT command
3. Issue At Command to get the new SMS.
4. the command will return the SMS sent time, message and sender ID.
5. you can do your logic after that.

OR

if you have project needed SMS Controller visit www.mypromosys.com, where you can find read-made unit with all the thing you need to archive.

Sorry having read my original question (written when I was very tired) I don't know if I've asked what I wanted answered.

I need either of those GSM modems to be able to send a SMS to a number rather than recieve an SMS.

That will be based on a command from a PIC. Sorry if there was any confusion.

Piers :D
 

Same rules apply, as mpathma said, just get a uC with a USART and learn AT Commands

Hi,


Yes, you can send SMS or received SMS using AT command, in fact you can do want a normal phone does with AT command.

If you need help on AT command tell me, I have very good experience in handling AT command.

:D Top Stuff! Thanks guys...
 

am having a similer problem , iw ant to design a simple system that can control devices at home via sms.
00: device 0 is off
01 device 0 is on
10 device 1 is off
11 device 1 is on

i have 2 pics's PIC16F84A and PIC 16F690
please the thing that i dont know(or rather blind) is how to connect my samsung j700 to the microcontroller, it has USB cable,it supports At commands,.
i need help please.
 

Excellent, that's great.

Are the boards available?

Added after 2 hours 34 minutes:

Also :D I'm intending on making this on breadboard first. Do you have alternatives to the BAT54's?

Fot the NPN's I was intending to use a 2N2222 and the PNP a 2N2905.

Should they be OK?
 

Hi,

I have still a few boards (without components) available.

Yes, you can use other diodes than BAT54 (eg. BAV70 if this
is SMD), BAT54 is a schottkey diode with at low voltage drop.

For the transistors you can just use ordinary NPN or PNP small signal
transistors, except for the one on Output3. This should be a 5-600 mA
version able to power the siren.

I have developed the software a little bit further, and put in some more
functionalities (2 phone numbers updateable by SMS). This is intented to
use an alarm system, an dif you like I can mail the the hex code.

Yes please to a board, let me know how much and how you want the money? PAYPAL :?:

I'm very interested in the new code, thanks.

I note you are using a Wavecom, I have one of those but I would like to connect a Nokia 5110 and use AT commands in the same way.

Have you considered setting a microphone/camera to the unit with remote activation to confirm the alarm is genuine and in the hope of catching the villan.. :D

I have PM'd my email

Hi Ole,

I am using your code as burglar alarm system using mcu 16f877a and found very much useful. I am intersted in your new code with multy phone numbers. It is very useful to me if you can post new basic code. I found this forum recently.

With thanks,
Mathew.
 

hi guys im working with similar project, do i really need to use two pics for this project? sms based switching?
 


I need that circuit can you send me please?
