This is a LoRa sensor node with an integrated SHT20 temperature and humidity sensor. The LHT65N is an updated version of the LHT65. Instead of an integrated battery, the LHT65N uses a 1x CR17450 3V lithium battery. Additionally, the included external temperature sensor is now connected via USB-C.

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

Use cases:

• Wireless alarm and security systems
• Home and building automation
• Industrial monitoring and control
• Long-range irrigation systems
• Agriculture
