MongoDB get individual fields?

Question

MongoDB

{"_id":"5cb0dfe234a8a30c9c0af127",
"sensors":
[{"value0":0.153,
"value1":-0.306,
"value2":9.807}],
"timestamp":1555095522489,"__v":0}

How to get 4 separate fields from this?
unwind only helps from the array, and the values ​​are still inside the object.
