senior and sensor differ by a single letter, buried far enough into the word to be easy to miss. senior means “older; higher in rank; longer in length of tenure or service”. sensor means “any device that receives a signal or stimulus (as heat or pressure or light or motion etc.) and responds to it in a distinctive manner”. senior is the more common of the two in everyday English.
