LHT65N E3 LoRaWAN Temperature and Humidity Sensor

This is a LoRa sensor node with an integrated SHT20 temperature and humidity sensor. The LHT65N is an upgraded version of the LHT65. Compared to the LHT65, the LHT65N uses 1x CR17450 3V lithium battery instead of an integrated battery. In addition, the supplied external temperature probe is now connected via USB-C.

The LHT65N is compatible with the LoRaWAN V1.0.4 protocol and can be operated via a standard LoRaWAN gateway. The LHT65N has 3200 retrievable data records, which are timestamped.
