What trademark class is sensor in?

Sensor sits in Class 9, software & electronics. That is where the USPTO's own ID Manual puts it: 102 accepted descriptions mentioning sensor fall in Class 9. Depending on exactly what you sell it can also fall in Class 10 or Class 42 or Class 25.

Do I have to file in more than one class?

You file in every class you actually use the mark in, and the USPTO charges its fee per class. Selling a product and also running an online store for it is two classes, not one. Filing in classes you do not use is worse than filing in too few: an application has to be supported by real use or a genuine intent to use.

Does the class decide whether my name is available?

No. The class decides what a registration covers. Availability turns on whether someone already holds a similar mark for related goods, and relatedness is judged on what the identifications say rather than on the class number, so marks in different classes can still conflict.
