Hi Folks,
Hope someone can provide some advice on where to start with this project I am working on. I need to use the PIC16F877A microcontroller to detect certain conditions (this part is easy) and when the correct conditions are met i need to send some basic information via a SMS text message to the owner or a few numbers. I want to use the simplest method possible to just send basic text data. I have looked at alot of GSM modems on the web and they all appear to come in large (approx 4"x4") units and are cost approx €150 e.g (**broken link removed**).
Any simple microcontroller to mobile phone communication method you can suggest would be appreciated and low cost too if possible. tnx..
