Dragino LWL02

The Dragino LWL02 is a LoRaWAN Water Sensor. When there is water between the two metal probes, LWL02 indicates a water leak event and uplinks to IoT server via LoRaWAN network. The LWL02 will send periodically data every day as well as for each water leak event. It also counts the water leak times and calculates the last water leak duration. This device is powered by 2 x AAA replaceable batteries.

Features Highlight

1 External probes
2 x AAA Batteries
Easy battery replacement
Battery life: 16,000 – 70,000 uplink packets
Water leaks counters
Count water leak duration
1 LED indicator

IoT Server Integration

Users can conveniently access and monitor water leak event, number of water leak, and the duration of leak through the connected IoT server.

Battery Powered

The LWL02, powered by two AAA batteries, is designed for long-term use, delivering an impressive range of uplink packets (approximately 16,000 to 70,000) before battery replacement is needed.

Periodic Data Transmission

The LWL02 sends periodic data updates every day, enabling continuous monitoring of door status. It also provides real-time updates for water leak events.

CASE STUDY

This case study explores the practical application of LWL02, highlighting the ability to detect and count water leaks.

Washing Room Monitoring:

By deploying LWL02 on the water connection of washing machine, and the washing machine drainage pipe.

1. 1. 1. Washing Machine Water Connector:
      In the event of a leak from washing machines or water pipes, the LWL02 detects water and triggers an immediate alert. This quick response helps prevent water damage and ensures the proper functioning of appliances.
    2. Drainage Pipe:
      Place the probe near the drainage pipe for the washing machine. So, the customer can get the notification when the water leaks.

Commercial Building Infrastructure Protection:

By placing LWL02 below the HVAC unit and bathrooms pipe

1. 1. 1. HVAC Unit:
      The LWL02 probes will detect the water leaks from the AC unit and will send the notification when the water leaks happen.
    2. Bathroom:
      When water leaks occur, the LWL02 probes will notify you and detect the leaks coming from the bathroom pipes.

Kitchen Water Leak Protection:

By installing LWL02 in a kitchen with the external probe strategically placed near sinks, dishwashers, and other water sources.

1. 1. 1. Water Leak Monitoring:
      If there’s a water leak in the kitchen area, the sensor promptly detects it and sends an alert.

Aquarium Water Level Monitoring:

The LWL02 is employed in a large aquarium or aquatic research facility with an external probe submerged in the water.

1. 1. 1. Water Level Monitoring:
      The sensor continuously monitors water levels. In case of a sudden drop or rise in water level, indicating a potential issue, the LWL02 sends an alert to aquarium staff.
