Detect Humanoids

For the duration, you sense the presence of living humanoid creatures within 60 feet of you. If you sense a creature in this way, you perceive a faint glowing outline around them with brightness corresponding to the creature's general health. You also learn the race of the creature, although if the creature is magically disguised or transformed, you only sense the race of the image or transformation.

The spell can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.
