The sensors data frame contains the responses of eight different semi-conductor element sensors to varying levels of a particular gas in a container of air. The engineers who designed these sensors were interested in determining the relationship between the responses of the sensors in order to determine whether or not they can make a more precise measurement of the concentration of the gas by using more than one sensor, at an additional cost, instead of single sensor.
This data frame contains the following columns:
The data was obtained from an unpublished report from the Center for Process Analytic Chemistry at the University of Washington.
