It is powered by three replaceable lithium batteries. The device is autonomous and has a built-in power supply, it does not need to be connected to the electrical network, which is especially important away from the benefits of civilization. In cases where animals have left the LoRaWAN network coverage area, the measured data is stored in the device's memory and subsequently transmitted in strict order (FIFO) to the cloud analytical platform when the device appears in the network coverage area.
