You have exported the class constructor function; you haven't called the
function anywhere to instantiate it.
If your intention is that multiple objects could be created, then you've
exported the right thing, and you need to call that function when you require
it, e.g.:
var sensor1_class = require('./sensor1_class');
var sensor1 = sensor1_class();
Alternately, if it is your intention that there be a single instance of this
object that every other file that requires the class shares, then you should
instantiate the object in sensor1_class.js and return that instance:
module.exports = Sensor1();
