DRAGINO Sensor LoRa water leak sensor LWL04-EU868

DRAGINO water leak sensor LWL04

Overview

The Dragino LWL04 is a LoRaWAN water leak sensor. When there is water between the bottom 3 metal posts, the LWL04 will indicate a water leak and send an uplink to the IoT server via the LoRaWAN network.

The Dragino LWL04 does not need to be fixed, just placed on the floor. The three lower metal columns can be adjusted in height. A short circuit alarm is only triggered if there is water between the three metal columns.

The LWL04 can be activated from the bottom of the case with a magnet, and the light will indicate when the magnet is close. The main unit has a sealing ring that can reach IP65 protection rating.

The LWL04 is powered by a non-rechargeable CR123A battery and is designed for long-term use. These batteries can deliver about 16,000 to 70,000 uplink packets, giving a battery life of 2 to 10 years. When the battery runs out, the user can easily open the case and replace it with CR123A batteries.

The LWL04 sends data regularly every day and whenever there is a water leak. It also counts the water leak times and calculates the duration of the last water leak. The user can also disable the uplink for each water leak event, instead the device can count each event and send the uplink periodically.

Each LWL04 is preloaded with a set of unique keys for LoRaWAN registration, these keys are registered with the LoRaWAN server and the device connects automatically after power on.
