Since usually connects ideas related to time or reasons. Sense usually refers to awareness, understanding, meaning, or perception.
Choosing the correct word depends on the role it plays in a sentence. If you are talking about when something started or why something happened, you usually need since. If you are talking about understanding, feelings, or perception, you usually need sense.
