Modern environmental monitoring systems are distributed systems, often with the integration of automated data collection and transmission processes. This approach allows to reduce the measurement error by eliminating the human factor, but sets a number of tasks to improve the efficiency of the system devices, including power consumption. The main consumer of energy in the device is the radio transmitter module. The article presents the calculations of the required energy for data transmission, depending on the selected parameters of the LoRaWAN radio module and the device operation algorithm, an estimate of the device operation time when using various transmission algorithms. With the introduced restrictions, the calculated benefit of the required energy for the transmission of one bit of information is up to 26% when choosing the optimal parameters of the transmitter and up to four times the operating time of the device from the battery with using varios depeloped algorithm of data forming and transmission.
