LW1 Water Leak Sensor

Contact Support

The LW1 is a long-range water leak sensor that detects water at multiple contact points and reports leak events through a compatible LoRa Hub.

LW1 Water Leak Sensor

The LW1 is a long-range water leak sensor that detects water at multiple contact points and reports leak events through a compatible LoRa Hub.

Core Functions

  • Detects water through bottom, side, and top contacts.
  • Sends leak events over long-range LoRa communication.
  • Supports Freeze Alert using temperature data reported to the cloud.
  • Provides a 105 dB local buzzer and an IP67-rated enclosure.

Water Leak and Water-Level Detection

The bottom and top each have a separate group of sensing contacts. Each group detects a leak independently. Low, medium, and high water levels require water at the corresponding side contacts and at either the bottom or top contacts.

StateTrigger condition
Bottom leakThe bottom contacts detect water.
Top leakThe top contacts detect water, such as water dripping onto the Sensor.
Low water levelThe bottom or top contacts detect water, and the side low-level contacts detect water.
Medium water levelThe bottom or top contacts detect water, and the side medium-level contacts detect water.
High water levelThe bottom or top contacts detect water, and the side high-level contacts detect water.

Water at the bottom or top contacts alone triggers the corresponding leak condition, but does not trigger a water-level condition unless the corresponding side contacts also detect water.

For example, if only the side low-level, medium-level, or high-level contacts are wet while both the bottom and top contacts are dry, the corresponding water-level condition is not triggered.

Temperature Data and Freeze Alert

LW1 reads temperature from a sensor inside its MCU and sends the reading to the cloud through a compatible Hub. The MOCREO Smart App does not display LW1 temperature readings or a temperature history chart; refreshing the App does not make these readings visible. The temperature-related feature available in the App is Freeze Alert, which relies on the reported temperature data rather than a user-facing temperature display.

Temperature data can be available through the API even though it is not shown in the App. LW1 is not presented as a general-purpose ambient-temperature monitor with a specified measurement range or accuracy. The operating temperature below describes the device's operating conditions, not its temperature-measurement range.

See LW1 temperature reporting for reporting behavior and limitations.
