The TP-Link Tapo T300 Smart Water Leak Sensor is a compact and reliable device designed to detect water presence through dual-probe sensors located at its top and bottom. Perfect for use under sinks, near washing machines, baths, basements, or any damp environment, this sensor offers early warning against water damage by instantly detecting drips and full immersion leaks. It features a powerful 90 dB adjustable alarm that alerts immediately upon leak detection, and has a one-touch mute function for convenience.

With an IP67 waterproof and dustproof rating, the Tapo T300 ensures robust performance in wet and dusty conditions. This smart sensor requires connection to a Tapo Hub, enabling it to trigger coordinated hub alarms and push instant notifications directly to your smartphone through the Tapo app. It also integrates with Tapo smart lights for visible alerts, enhancing your smart home ecosystem.

The device is powered by two AAA batteries (included), providing long-lasting operation with a battery life expectancy of up to 1.5 years under typical usage scenarios. Installation is quick and easy, supported by multiple mounting options like adhesive strips, lanyards, and magnets to fit in virtually any space. Its compact size (84.5 × 46.5 × 30 mm) and wide operating conditions (0–40°C temperature and 0–99% relative humidity) make it ideal for continuous monitoring to protect your home or business from costly water damage.
