WEIGHTED LEAST-SQUARES POLYNOMIAL APPROXIMATION EMPLOYED TO RH SENSORS CALIBRATION POINTS
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2012, Vol 59, Issue 260
Abstract
Weighted least-squares method was applied to derive polynomials which approximate the transfer functions of relative humidity (RH) sensors. The formulae for typical cases were discussed. The exemplary results were compared to the calibration equations obtained by the ordinary least-squares method and those presented in datasheets, and the conclusions were drawn.
