Abstract
An optoelectronic two-wave method is proposed for the remote monitoring of the moisture content in raw cotton. To develop this method, the absorption spectra of wet and dry cotton were compared and the optimal wavelengths for the measuring and reference channels were determined. An operational algorithm and a block diagram of the infrared sensor proposed for this method are provided. For the reference channel, light-emitting diodes (LEDs) with an emission spectrum maximum of 2.2 μm were used, whereas LEDs with an emission spectrum maximum of 1.94 μm were used for the measuring channel.
