Abstract
This thesis examines the development and current practical application of environmental parameter measurement, focusing primarily on air temperature, relative humidity, and air pressure. The literature review presents early forms of observation, the main stages in the evolution of measuring instruments, and the key issues of measurement accuracy, calibration, standardization, and data quality. The practical part introduces the design and implementation of a self-developed, low-cost, scalable sensor network. The system is based on wireless ESP32 endpoints, BME280 and SHT40 sensors, and a Kubernetes-based cloud architecture for data ingestion, storage, and visualization. The measurement campaign, carried out at two locations with a total of 13 endpoints, produced more than 2.7 million records. The results confirmed that the system operated reliably and was suitable for comparing sensors, detecting differences between rooms, and identifying short-term microclimatic changes related to residential ventilation, cooking, bathing, and similar everyday events.
