Good day.

I'm looking to add GSM notification capability to a security system. I've found some GSM modules on ebay, such as http://www.ebay.co.uk/itm/Arduino-Wireless-GSM-SIEMENS-TC35-SMS-Module-UART-232-/320771809651?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item4aaf7d6173


I need a device, which will calls specified number, when relay is triggered.

I've searched in the forum, there are a lot of topics which talks about PIC controllers. Question is, will I be required to built and additional circuit, to support GSM module, or do they come already as a "ready to use" module. And I think above link also will require controller, as it says it is controlled via AT commands...

Any links where I can enhance my knowledge about GSM modules/security systems/programming will be appreciated. Also, any particular good GSM modules, recommend pls where to buy

Thanks
