Selection of a microcontroller for a measuring complex

Abstract

To create a measuring complex for clonal micropropagation of plants, the choice of a microcontroller begins with defining the system goals and measurement parameters. In this work, we will focus on the problem of measuring humidity in the range of 80–100%. It is important to consider the accuracy, range of operating conditions, autonomy and power consumption. The requirements for the number of interfaces (I2C, SPI, UART) and ADC channels depend on the number of sensors and their polling frequency.
