LHT65N-VIB
LoRaWAN Low Cost General Vibration Detection Sensor
The Dragino LHT65N-VIB LoRaWAN Vibration Sensor is designed to detect and measure vibrations, shocks, or accelerations of an object. By analyze the motion of the object, LHT65N-VIB can send meaningful resulte such as: Alarm, device runtime, counting, vibration strenght to IoT platform for further analyze. It targets professional wireless sensor network applications such as monitoring equipment status, water leakage alarm, usage statistics, vibration intensity detection, etc. The LHT65N-VIB allows users to send data and reach extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. LHT65N-VIB has a built-in 2400mAh non-chargeable battery which can be used for more than 3 years*. LHT65N-VIB is fully compatible with LoRaWAN v1.0.3 Class A protocol, it can work with a standard LoRaWAN gateway. *The actual battery life depends on how often to send data, please see battery analyzer chapter.
Application guide
Choose the airflow range by deployment scenario
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.
