The device joins OTAA to the LoRaWAN / The Things Network and transmitts every 15min the actual data (distance read from serial). If the data is "0" or "500" it will repeat the reading because that will be a error (the sensor range from 500 to 9999mm). If the distance is changing to fast (a hound swimming under die sensor, or a canoe at the time of reading) the node will switch into a fast reading sequence reading and transmitting every 5min till the distance change is inside the normal behaviour again.
