Supervision multidistribuida de un secadero solar de madera empleando sensores de bajo coste

Abstract

Multi-distributed supervision of wood in solar dryers is carried out by means of high performance low cost ambient sensors. An experimental dryer of 0.3 m 3 is used for testing the proposed instrumentation mainly based on thermocouples and SENSIRION TM which are combined with the psychometric model defined by ASABE in order to assess the amount of water released by the wood during the drying process. Continuous monitoring enables the Implementation of automated control of the dryer by means of regulating the fan speed and the amount of re-circulated air
