Měřicí a vizualizační systém pro měření environmentálních veličin s využitím technologie IQRF

Abstract

With the development of modern technologies and materials, and sometimes also for economic reasons, the work environment is deteriorating in some cases, which can lead to health problems. One factor is an increased CO2 concentration due to a better sealing of the building envelope. It is therefore necessary to monitor the air in the living quarters and, on the basis of the data, to take effective measures. That is why the subject of this thesis is the design and implementation of a measuring instrument and training modules for monitoring of selected environmental quantities in rooms using IQRF technology. Measured quantity of carbon dioxide concentrations, temperature, humidity, atmospheric pressure. The sensors are connected to the IQRF transceivers via the I2C bus. These IQRF transceivers communicate with each other through the IQMESH network. Communication on this IQMESH network uses the DPA protocol. The measured data is stored in the MySQL database. Data visualization takes place in the Node-RED and Grafana environment.
