Hello all,
I'm going to send analog signal by GSM modem, after using a PIC, then to receive it by another GSM modem, then display it on the computer,

can you tell me:

  • which GSM modem I have to use?
  • what type of PIC's shall I use, knowing that I will send 2 or 3 signals at once?
  • can you support me with any related diagrams?


Thank you all in advance.

My best regards.

    how will you send analog signal using GSM modem? are you planning to send an sms with analog values? or use DTMF?

    Any pic with the required number of ADC's will do. It should also have provision for RS232 Communication.

    Yes we are planning to send an sms with analog values.
    and I know we will use a pic that supports ADC 😀
    but which GSM modems do you recommend me to buy?

    Well, I think the most common and cheapest one available around is Sim300 based modules around 3-4k. Works well. checkout #-Link-Snipped-# I bought it from them and it has been put to real-time usage.
