No, Divine Sense 5e does not detect alignment. Older editions of DnD let players detect alignment, but this feature was almost entirely removed in the 5th edition. The only way to detect alignment in DnD 5e is with a Glyph of Warding, which can be set to go off for specific alignments. Jeremy Crawford even confirmed this on Twitter in April 2018: “Divine Sense doesn't detect alignment or curses. The feature's text explains what it means by strong evil and good: fiends, undead, celestials, desecration, and consecration.”
