Background. Control of moisture and impurities of agricultural products is the main production task affecting their quality, reduction of energy consumption during storage and processing, cost, technical and nutritional values, availability of useful consumer properties. Materials and methods. A two-stage method for determining moisture and impurities in products is proposed, the study of which is carried out by computer modeling in the SimInTech environment with obtaining the results of model calculations in real time based on programmable blocks. Results. A simulation model of the proposed method is constructed and the results of its calculation are obtained in comparison with the known method for determining the parameters of measuring circuits. A functional scheme of the proposed information and measurement system for monitoring humidity and impurities of agricultural products has been developed. Conclusion. The results of the calculation showed that the proposed method has a significant advantage in terms of the relative error of the results of determining informative parameters.
