Dear Friends I need data acquisition and controller circuit through gsm and gprs modem
I have to search but i cont get the best circuit Please help me anybody :roll::thinker:
 

how many channels of data acquisition, how many bits converted by the ADC, how fast, etc?
what do you want to control, e.g. how many devices, how are they attached (I2c, SPI, CANBUS, etc)

to aid in selecting a target device you can use product selectors, e.g. Microchip

you can connect a GPRS modem to the UART (pins 25 and 26 of PIC18F4550) and send AT commands
if do a forum search on GPRS modem it will give you plenty of links to posts on the subject
