The TP-Link Tapo T300 is a smart water leak sensor designed to provide early detection of water leaks, preventing potential water damage and costly repairs. It sends instant alerts to your Tapo app when a leak occurs, allowing for a quick response. This sensor operates within a temperature range of 0 to 40°C and a humidity range of 0 to 99%. It is powered by AAA batteries for wireless installation and can be placed in strategic locations such as near washing machines, sinks, and water heaters. The Tapo T300 features 6 high-sensitive probes that detect both drips and leaks, and it has an integrated 90 dB alarm. It also supports integration with Tapo smart bulbs for visual alerts and requires a Tapo Hub to trigger its alarm, with one hub supporting up to 64 sensors. The sensor has an IP67 waterproof and dustproof rating, making it suitable for humid and dusty environments. With two AAA batteries, it offers a long service life, lasting up to 1.5 years when coordinating with Tapo Hub alarms or over 2 years when working independently.
