LoRaWAN Water Leak Sensor

LoRaWAN Water Leak Sensor


The LWL01 is a long range LoRaWAN Water Leak Sensor that can be used to detect water leaks or water levels in a wide range of applications. It is triggered by the two probes coming into contact with the same water. The default events are:

  • A “heartbeat” message which is sent once per day
  • An emergency event message when a water leak is detected (can be disabled)
  • A periodic update every 10 minutes when water leak is ongoing
  • A message when the water leak is no longer detected (can be disabled)

The LWL01 is extremely compact, 64 x 30 x 14 mm, and can be placed in very tight locations.

Product Description

The LWL01 is powered by a CR2032 coin battery and in a good LoRaWAN network coverage case it can transmit as many as 12,000 uplink packets (base on SF7, 14dB). In poor LoRaWAN network coverage, it can transmit ~ 1,300 uplink packets (base on SF10, 18.5dB). The design goal for one battery is up to 2 years. The CR2032 battery can easily be replaced.

The LWL01 will send one “heartbeat” message each day to indicate it is alive, and to pass the battery level. It will also send an uplink on any water leak event. The sensor also keeps count of the number of times a water leak has been detected, and the duration of the last water leak.

Each LWL01 is pre-load with a set of unique keys for LoRaWAN registration. Register these keys to any LoRaWAN server and the sensor will auto connect after power on.
