description: This final qualification work is devoted to the development of a micro-controller environmental sensor based on the BME680 chip, which measures such climatic indicators as temperature, relative humidity, atmospheric pressure, and the content of volatile organic compounds in the air. The scope of the designed device was determined: the sensor can be used to measure microclimate in industrial prem-ises, in high-precision measurement laboratories, as part of the Smart Home sys-tem, etc. Quantitative values of environmental parameters for monitoring working conditions were studied. A structural diagram is compiled and the main features of the elements are described in detail: four sensors of the BME680 microcircuit, where particular interest is shown in assessing air quality; STM32L431CCT6 mi-crocontroller operating modes with ultra-low power consumption; LoRa SX1276 wireless module architecture. The principle of operation of the network serial inter-face of the I2C data exchange is considered. The concept was developed in the EsyaEDA web environment. A PCB trace was also manually made there. The dilut-ed sensor is ready for the manufacture and soldering of individual elements. The analysis of the results obtained.
