LWL02
LoRaWAN Water Leak
The Dragino LWL02 is a LoRaWAN Water Leak Sensor equipped with two external metal probes. When water is detected between the two metal probes, the LWL02 identifies a water leak and sends an uplink to the registered LoRaWAN network server. The LWL02 is powered by 2 x AAA batteries and is designed for long-term use. These two batteries can support approximately 16,000 to 70,000 uplink packets, resulting in a battery life of 2 to 10 years. Once the batteries are depleted, users can easily open the enclosure and replace them with standard AAA batteries. The LWL02 sends data periodically every day and also for each water leak event. It records the number of water leak occurrences and calculates the duration of the most recent leak. Users can disable uplinks for each individual water leak event if desired. In this case, the device will count each event and send the data periodically.

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.
