Abstract

First results for luminescence-based dual sensing of environmental parameters with a multicolor LED are presented. With this method, cross-sensitivities of the luminescence material between such environmental properties can be eliminated. A very compact and inexpensive sensor setup is possible by use of an LED as excitation source and another LED simultaneously as luminescence detector. The parametrization of the cross-sensitivity will be discussed and possible further simplifications of the sensor will be pointed out.
