Question

I have created an ontology. There is a temperature sensor class and humidity sensor class. the can have sensor values.

Now I want to define a class where if the temperature sensor has value less than 25 and humidity sensor has value less than 20 then it will define a normal state. I m not sure should I define a class or something else. In the result I want that when a temperature sensor's and a humidity sensor's value is less than defined rule I can call them as a member of normal state. but any of the sensor violate the rule neither sensor will be the member of that class
