The main information parameters of the microclimate of greenhouse premises are substantiated, in particular: air temperature, relative humidity, illumination of greenhouse premises, soil temperature, soil humidity, the concentration of carbon dioxide. The cyber-physical system for vegetables’ cultivation with the regulation of temperature-humidity-insolation regime contains three subsystems, namely the subsystem of temperature control, the subsystem of humidity control, and the subsystem of insolation control.
The possibility of creating inexpensive and widely available real-time signal processing devices to solve scientific and technical tasks based on a microcontroller, which is an alternative to the use of specialized digital signal processors, has been investigated. It is shown that the bit rate, clock speed, instruction speed are the basic parameters that are necessary for the implementation of algorithms for digital signal processing based on the microcontroller.
An automated cryostat temperature control system for low-temperature galvanomagnetic measurements has been proposed. The automated system works autonomously with a microcontroller. A system for controlling the power of the heater in the thermostat is operated by the means of pulse-width modulation. The automated control system is based on standard equipment and it is easily available for practical application.
This article is devoted to the design of a system to detect gases. The paper describes a system that is based on the controller STM32F4 and includes a series of sensors MQ. System requirements were formulated, the software was developed.
