Compact System for Autonomous Meter Reading
Podeszwa, David ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
This work solves the problem of the insufficient range of WMBUS meters, which makes their reading still difficult. The developed implementation solves this problem by using a battery-powered device that extends this range by using a LoRaWAN network, where the data received from the meters is sent over this network for further processing. The created device is capable of receiving WMBUS frames and sending them for a minimum period of 9 years. The main benefit of this work is the implementation of such a device on the new STM32WL platform, which is unique due to its integration of a microprocessor and a Sub-GHz receiver inside one chip.

Measuring Station Firmware for LoRaWAN Wireless Data Collecting
Janos, V. ; Juran, R.
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.
