GOSUND S5 WiFi Smart Water Leak Sensor with Tuya App Alerts, 2.4GHz, IP67 Probe, White

Detect water leaks in under one second and get instant push alerts on your smartphone, even when you're away. The GOSUND S5 WiFi Smart Water Leak Sensor combines a rapid-response probe with reliable 2.4GHz Wi-Fi, making it a practical safeguard for kitchens, basements, bathrooms, and utility rooms.

Overview

The S5 is a compact, surface-mounted sensor that sits directly on the floor or near potential leak sources. Its exposed metal probes trigger an alarm the moment they contact water, sending an immediate notification through the Tuya Smart or Smart Life app. With a standby current of less than 10 µA, the sensor runs for up to 12 months on two AAA batteries (not included), and you'll get a low-battery alert before power runs out.
