The NOUS E13 is a compact, wireless smart home water leak and water shortage sensor that uses the reliable Zigbee 3.0 protocol for communication. It automatically detects the presence or absence of water at a given point and immediately alerts users with a local audible alarm and a push notification via the mobile app.
The E13 is an ideal choice for monitoring humid environments, such as bathrooms, basements, under washing machines or sinks, around aquariums, or for monitoring water tank levels. Thanks to its built-in 80 dB siren and IP66 rating, it can be safely placed directly in high-risk areas and withstand exposure to moisture and dust.
