LWL04
LoRaWAN Water Leak Sensor
The Dragino LWL04 is a LoRaWAN Water Leak Sensor. When there is water between the bottom 3 metal posts, the LWL04 indicates a water leak event and uplink to IoT server via LoRaWAN network. The Dragino LWL04 does not need to be fixed, only placed on the ground. The bottom three metal columns can adjust the height. Only when there is water between the three metal columns, it will cause a short circuit alarm. LWL04 can be activated from the bottom of the housing with a magnet, and the light will indicate when the magnet is close. Its main unit has a sealing ring, which can achieve IP65 waterproof.

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.
