REMOTE CONTROL: Detector alerts can be connected to WiFi and an app, so even if you're not home, you'll receive real time warning notifications when there's a leak or water seepage. LOW BATTERY ALERT: When the sensor is low on power, the indicator light may flash once a minute and beep, indicating that the battery needs to be replaced as soon as possible (excluded). COMPACT SIZE: Our compact size of this sensor is easy to install, and the installation does not take up space and is responsive.
