Autodialer system

46pp6q

Hi all, first time poster !! Hope im in the right area.

Im looking for some info on the internals of an autodialer or a unit that can send a txt message.

The unit would ideally use a no volt or low volt imput that would be activated by an external switch, be that a door switch or an auxillary contact on an electrical overload etc.

My question is how would i go about building said unit myself ( plenty of engineering and electrical experience but not so much electronics) or what about companies that could design a simple unit.

Ive been looking online but mostly its just companies advertising their products and that sort of stuff.

Thanks in advance guys !!!!

Thanks Gate Automation, not really what i was looking for, im after a basic PCB with room for a sim card, i dont want to just buy an autodialer off the shelf i would like find out more about the bare electronics and see if i can incorporate into a bigger control circuit.

Thanks for your reply

Get a telit gsm module you can program it via python and read in analog / digital inputs. Or a gsm shield and an arduino? If you have Ethernet available use an arduino and Ethernet shield, very cheep solution.
