120 Ac voltage sensor

Im looking to monitor 120 volts ac with a pi. Is there a sensor that can do that or do i need to go the route of using a transformer with a sensor?

Re: max31855 and node red

The link you provided is the link that i had followed. I installed it and then node red crashed and i had to reinstall everything. I tried it again after a fresh install and the same thing happened.
