Clairvoyance

You create an invisible sensor within range of the spell in a location familiar to you (a place you have visited or seen before) or in an obvious location that isn’t familiar to you (such as behind a door, around a corner, or in a grove of trees). The sensor remains in place for the duration of the spell and can’t be attacked or interacted with.

When you cast the spell, you choose to see or to hear. You can use the chosen sense through the sensor as if you were in the space it occupies. As an action, you can switch between seeing and hearing.

A creature that can see the sensor (such as one benefiting from see invisibility or true sight) sees a luminous, intangible orb about the size of a fist.
