The use of a microcontroller as part of a device for measuring humidity using the thermogravimetric method is considered. The main nodes of the device have been designed, in which the microcontroller receives and processes information from them, and also controls these nodes. They use various microcontroller capabilities, including several data transfer interfaces: I2C, SPI, etc. A built-in analog-to-digital converter is used. The power control unit allows you to flexibly set the required heater power in the device. A unit has been created to control the mass of a material sample in the drying chamber of the device, which provides an accurate measurement of the mass of the substance. The temperature control unit allows the microcontroller to evaluate the material drying parameters and select the operating mode of the power regulator. The performance of the designed units was tested. It is noted that they can be used in a device for measuring humidity using the thermogravimetric method under the control of a single microcontroller.
