Default Phase sequence

I want to build a new phase sequence detector...
I have one implemeted using a triac, diodes and 4093 and it works!
There are any other way or a different aproach to detect the phase sequence (using microcontroller´s or some other components...????)

The phases are 120 degrees apart, which corresponds to a time delay of 5.56 milliseconds (at 60 Hz) between each phase.
