Author Experience and Unit Operation:

One of the Most Interesting Project of My Professional Career

In this Project "USER" was given Privilege to Operate "MOTOR" situated in Agriculture Farm from anywhere By Calling GSM SIM900 module and Just Pressing Key on the Cellphone

✴ AT COMMANDS ✴
AT --> Attention
ATE0 --> Turn Echo Off
AT+DDET=1 --> Enable DTMF Detection Functionality
ATS0=2 --> Automatically Pick Up Call after Two Rings

So Firstof All USER Calls the GSM SIM900 module
After 2 Rings GSM module Automatically Picks Up the Call
After that USER should Press the Key on Cellphone
After USER Presses Key on the Cellphone....GSM module Responds with a Stream of Data

If USER Presses '1' then response of GSM SIM900 module will be "+DTMF:1"
If USER Presses '2' then the Response is "+DTMF:2"
If USER Presses '3' then response is "+DTMF:3"

and So on....

In this Way USER can control the "MOTOR" using GSM SIM900 module
