An optical sensor determines a characteristic of a fluid medium based on a plurality of detector outputs and a characteristic model. The optical sensor directs light into the fluid medium, detects light at each of a plurality of wavelengths transmitted through the fluid medium, and produces therefrom the plurality of detector outputs. The characteristic model provides an estimate of the characteristic of the fluid medium based on a partial least squares analysis of optical transmission measurements through at least one reference fluid medium having a known characteristic.

Fluid property determination based on partial least squares analysis

A dryer monitoring system receives dryer information from one or more sensors concerning operation of one or more dryers, such as clothes dryers. For example, the dryer monitoring system may receive temperature and/or humidity information from one or more dryers. The dryer monitor analyzes the dryer data to determine whether textiles in the dryer are dry. The dryer monitor may analyze one or more states and/or one or more indicators (patterns in the dryer data) during the dryness determination.
