Welcome to our store! This is a smartly designed practical water leakage alarm that is easy to install and easy to use. It has low power consumption and a reverse polarity protection design, so you don't have to worry about burning it out. When water is detected, the alarm emits a loud 120DB sound to warn you until the water is dry or the sensor is turned off. It comes with a sensor size of 30*12 mm and an alarm housing size of 98*46*22 mm. The line length is approximately 1 meter and the required battery is a 9V battery (not included).

Please note that after the alarm has sounded, make sure to dry the water on the sensor to avoid continuous alarms. Also, please note that the alarm housing is not waterproof, so it should be kept away from water.
