Nowadays, the development of electronics and related technologies is very fast. An extremely significant role in the life of moder society is took by information output devices, the development and modernization of which is an urgent task. Using the idea regarding wireless control of remote devices, an information board with remote control was developed. This article provides a reader with the development of universal information board which customers will be able to assemble for the dimensions that they need.
With the development of microprocessor components and, accordingly, a significant expansion of the use of computer technologies, remote measurement techniques are being developed. These include telemetry and remote control of technical systems or their components in industry, research, home appliances and other fields. In this paper, the author suggests how to build a local web-server based on a microcontroller with an ARM Cortex-M4 core, which can be interacted with via an http-browser with Internet access.
An alert system has been studied, in which sensor data can be collected and analyzed for further processing and action. Notifications are generated when data is compared against certain criteria. The ESP8266 microcontroller has been chosen as the basic device for implementing such a system, as this Espressif controller is a highly integrated Wi-Fi SoC solution that meets the demands of the cyberphysical systems industry in low power consumption, compactness and reliability. This solution is one of the most effective for the alert system.
In this project was shown approaches to the implementation of a weather station for monitoring the microclimate in the room on Arduino platform. Considered a platform for project development and software environment. The virtual scheme of the weather station is modeled. The main functions of the components are described and their connection to the microcontroller is shown. The process of firmware of the microcontroller is considered. The algorithm of system operation is described. A functional electrical diagram were also constructed.
In today’s reality, the pace of people’s lives is much higher than it was 30 years ago and it is still growing. At the same time, the amount of information also growing. This information should to be processed constantly, daily, as soon it is received. Production volumes are also not standing still. Such a lively pace of life requires process consistency and continuity. And these processes must be provided by man.
The issue of creating an IP camera based on the ESP-32 CAM module, and integration and transfer of images to the messenger is considered. Provision is made to ensure and increase security during data transmission and interaction with the bot. It is also proposed to create a special telegram bot, using the telegram API, to obtain images from the camera, at any time, when connected to the Internet. The efficiency of the microcontroller at a given task is analyzed. The use of MQTT transmission protocol is proposed, and its advantages for this system are considered.
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.
