Measuring Station Firmware for LoRaWAN Wireless Data Collecting

Abstract

This paper describes the software side of the outdoor carbon dioxide flux low-power measuring station prototype. In the following lines, the selected chamber measuring method is described as well as the IoT protocol LoRaWAN, which is used in this project. The principle of measuring software and following data processing is also introduced. Controlled parts are thermometer, CO2 sensor, and chamber fan. The device is intended to be used in places that have natural sources of carbon dioxide. Measured data are sent through the LoRaWAN network for visualization and further evaluation.
