How many AOA sensors does the 737 MAX have? How many AOA sensors does the 737 MAX have?

Given that it's reported in the media, that one faulty AOA probe activated the MCAS on the Lion Air flight, I was wondering if anybody also knows how an input consensus is reached for the AOA value that gets send to the MCAS system.
The Boeing 737 MAX has 2 AoA sensors.

However, MCAS only takes input from 1 AoA sensor at a time.



Sources:

The black box flight recorder data for Lion Air JT610 shows the data from 2 AoA sensors, labeled "Left" and "Right".

Also, if you look at the nose of the 737 MAX, you will see a left and right AoA vane. (The sensors with the red tags are pitot tubes).

"[Boeing] said it will change the MCAS software to give the system input from more than one AOA sensor."
