LoRa measuring system

Modifying firmware to increase the distance over which the sensors (transmitters) can reliably communicate with the receiver at frequencies of 169 MHz and 869 MHz. LoRa modulation was used as a solution. After proper adjustment of the modulation parameters, we reached a distance of approximately 45 km in line-of-sight in the testing stage, which was a significant improvement over previous results.
