LHT65N/S-DS

LoRaWAN Door 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*.

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.

  1. AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
  2. LoRaWAN gateway receives data from distributed sensors across the site.
  3. Cloud platform visualizes trends and helps trigger maintenance decisions.
