Interfacing microcontroller

We're working on a project about flood monitoring system. the idea of the
system is like this, we will put a sensor on places where flood rise whenever
it rains which is also connected to a cellphone,then when the flood reach a
certain height then it will send a signal to the cellphone and the cellphone will
send a message to our University Administration to know the situation in the vicinity of our university especially when the rain occurs early in the morning and also to the pumping station to let them know that they need to
open the pumping station to lessen the flood. The problem is, and we want
to ask for your help... How to interface microcontroller unit to a cellphone
(GSM) phone? What type of microcontroller is the best for our project? And
someone here know something about Nokia F-Bus Protocol?

Thank you in advance!

hi kiccomachine19,
i think you are at the right place there is already a discussion going on implementing Nokia FBUS protocol on AT89C52 microcontroller. One of the member is working on this project. I have some documents which he used in his project.
I will tell him to assist you in interfacing and implementing FBUS for your project.
Here is the FBUS protocol document he sent me..


Which nokia handset you are planning to use. This document seems to have information for Nokia 3310 mobile I am not sure if this also implies to all FBUS operated handsets.
