--
  LHT65N-PIR is configured as LoRaWAN OTAA Class A sensor by default. Each LHT65N-PIR is shipped with a worldwide unique set of OTAA keys. To use LHT65N-PIR in a LoRaWAN network, first, we need to put the OTAA keys in LoRaWAN Network Server and then activate LHT65N-PIR.
  If LHT65N-PIR is within the coverage of this LoRaWAN network. LHT65N-PIR can join the LoRaWAN network automatically. After successfully joining, LHT65N-PIR will start to measure environment temperature, humidity & people activity, and start to transmit sensor data to the LoRaWAN server. The default period for each uplink is 20 minutes.
