The object is a portable device for measuring the moisture content of grain under the conditions of the elevator. The purpose of the research work is to develop a device that allows you to repeatedly analyze the moisture content in the grain. The device is designed to measure the moisture content of the grain directly when entering the elevator, at the sampling site and controlling the moisture content during its storage, processing and delivery of finished products. It must satisfy the following requirements: the measurement limits are from 10 to 30% in two ranges. The measurement error in the first range is from 10 to 20% not more than 0.4%, and on the second from 20 to 30% - no more than 0.5%. The device is powered by a battery. The capacitance of a capacitive sensor with an uncleaned humidity sensor should be 3.2 pF. The transistors used in the device must have a static current transfer factor of at least 20.
