The paper focuses on designing and implementing a comprehensive monitoring system that enables long-term monitoring and visualization of selected environmental quantities, particularly in the interior of buildings, using modern SW instruments. For this case the measured quantities include concentration of CO2, temperature, humidity and ambient pressure. The device component of the sensor uses sensors from Figaro CDM7160, Bosch BME280, and Microchip MCP9802. The IQMESH network is based on the advanced wireless IQRF technology which allows the wireless monitoring system to cover vast areas. Measured data from individual measurement modules is sent to the native IQRF cloud storage using Raspberry Pi or via commercial Internet gateways. From there, it is transmitted via a script to a MySQL database running on the university site server, which can then be processed and visualized using the Grafana SW program.
