Introduction
The MOES Tuya ZigBee 3.0 Water Leak Sensor is a smart device designed to detect water leakage and flooding in your home or office. It monitors two states: from no water to having water, and from water to water receding. When water leakage or soaking occurs, the event is recorded in real-time through the connected app via your ZigBee gateway, allowing for immediate alerts and potential automation with other smart hardware products. This product is suitable for residential homes, buildings, factories, shopping malls, and office buildings.

Operating Instructions
The MOES Water Leak Sensor provides intelligent protection by continuously monitoring for water presence. When water is detected, it triggers an alert through the connected app.

The sensor is designed for intelligent protection, providing early warnings for potential water damage.

Upon detection of water, the sensor will trigger an abnormal alarm, which is reflected in the app.

Maintenance
Battery Replacement
The sensor is powered by a CR2032 battery. When the battery is low, replace it promptly to ensure continuous protection.
Battery Safety Warnings:
- Remove and immediately recycle or dispose of all batteries according to local regulations and keep away from children.
- Do NOT dispose of batteries in household trash or incinerator.
- Even used batteries may cause severe injury or death. Call a local poison control center for treatment information.
- Non-rechargeable batteries are not to be recharged.
- Do not force discharge, recharge, disassemble, heat above 80°C, or incinerate. Doing so may result in injury due to venting, leakage, or explosion resulting in chemical burns.
- Ensure that the battery is correctly inserted into the battery compartment according to the polarity marked, and the positive and negative poles cannot be installed reversely.
- Do not mix old and new batteries, different brands, or types of batteries (e.g., carbon-zinc or rechargeable batteries).
- Remove and immediately recycle or dispose of batteries from equipment not used for an extended period of time according to local regulations.
- Always completely secure the battery compartment. If the battery compartment does not close securely, stop using the product. Remove the batteries and keep them away from children.
