Voltage conversion

Sir I’ve a little problem arising in my project, it states “checking the status of line voltage through GSM with 8051”. I’ve almost done but the voltage conversion retard me to move on. I need your help if someone has idea that how one can make a logic to convert the AC voltage values through ADC. (remember while interfacing with 8051)
