LHT65N-E31F
LoRaWAN Temperature & Humidity Sensor
The Dragino LHT65N/S Temperature & Humidity sensor is a long range LoRaWAN end device. It includes a built-in Temperature & Humidity sensor and features an external connector to connect to an external Temperature Sensor. The LHT65N/S allows users to send data over extremely long ranges. It provides ultra-long-range spread spectrum communication and high interference immunity while minimizing current consumption. It is designed for professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, and more. LHT65N/S has a built-in 2400mAh non-rechargeable battery which can last up to 10 years*.

Application guide
Choose the airflow range by deployment scenario
0–5 m/s range
Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.
0–10 m/s range
HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.
0–30 m/s range
Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
