Zigbee Wireless Water Leak Sensor: Smart Home Flood Detection with App Alerts

Protect your home from the costly damage of unnoticed water leaks with this Zigbee wireless water sensor. Designed for integration into a smart home ecosystem, this compact detector monitors areas prone to flooding, such as under kitchen sinks, near washing machines, water heaters, or basements. Upon detecting water, it communicates via the Zigbee protocol to a compatible gateway, triggering an immediate alert on your smartphone through the supported Smart Life or TUYA app. This provides an early warning system, allowing for quick intervention to prevent extensive water damage. The device is certified with FCC ID and CE authentication, meeting specific regulatory standards for electronic devices.
Features and Construction

This sensor combines essential smart home functionality with practical, low-maintenance design for reliable leak detection.
Material and Build
The sensor housing is constructed from PC (Polycarbonate) material, chosen for its strength and durability to protect the internal electronic components. This material provides a robust enclosure suitable for the environments where water sensors are typically placed, such as utility cupboards or under appliances. The build is focused on housing the detection probes, Zigbee radio module, and battery compartment securely.
Size and Practical Fit
With dimensions of 50mm by 17mm, the sensor features a notably compact form factor. This small size allows for discreet placement in tight, often overlooked spaces where water might pool first, such as directly under pipe joints or in the drip trays of appliances. Its low profile ensures it doesn't obstruct other items or become an obstacle in cabinets or behind furniture.
Uses and Placement

The primary use case is preventative monitoring in residential settings, providing peace of mind for homeowners and landlords alike.
Event or Professional Use
For property management or holiday home monitoring, this sensor can be part of a remote oversight system. When integrated with a smart home hub that supports remote notifications, it can alert a manager or maintenance person to a leak event even when the property is unoccupied, enabling a faster response to mitigate damage. Its specified working temperature range of -10°C to 55°C allows for deployment in unheated garages, boiler rooms, or holiday caravans during colder periods.
Everyday Home Use
In a standard household, it is practically deployed in high-risk zones. Common installation points include under kitchen and bathroom sinks, behind dishwashers and washing machines, near the base of water heaters, and in basement corners or near sump pumps. The goal is to catch leaks from faulty appliance hoses, slowly dripping taps, or condensate drain failures before they saturate flooring or cabinetry.
Benefits and Buying Value

The value lies in damage prevention, smart integration, and straightforward maintenance.
Reuse and Low Maintenance
The device is designed for long-term use with minimal upkeep. Its power is supplied by a standard, user-replaceable CR2032 battery. The manufacturer states a battery working life of more than one year under a typical usage scenario of 20 detection events per day. The inclusion of a low battery warning via the app helps plan for timely replacement, avoiding gaps in coverage. The sensor itself, being a solid-state electronic device with no moving parts, requires no regular cleaning or calibration beyond ensuring the detection contacts are free of debris.
Why Choose This Product
This sensor offers a focused solution for integrating water leak detection into an existing or new Zigbee-based smart home network. Its key differentiators are its specific Zigbee protocol compatibility, compact size for versatile placement, and the practical benefit of a long-life, replaceable battery. For users already invested in a Zigbee ecosystem via brands like Samsung SmartThings, Amazon Echo, or TUYA-compatible hubs, it provides a specialised, affordable sensor to fill a critical safety gap in home automation. The regulatory FCC and CE certifications provide assurance of compliance with electromagnetic and safety standards.
