Best guess: he has powers as the plot demands and you could make a case for either... Which is not helpful I assume.
I think he probably would be if he is sniffing something out...not necessary 'is a woman in my vicinity using tampons atm?' But a general he is searching for sb. or sth. And focusing on the smells specifically.

(Disclaimer: not a comic reader and the explanation of his senses in the show is suboptimal)
