The leak sensor is designed for early detection and instant notification in case of flooding.

The device detects minimal flooding from 1.5 mm. When operating autonomously, it emits a sound signal with a volume of up to 65 dB / 3 m.

You need the sensor's connection to Perenio Control Gateway via the app for remote control and receiving push notifications. The device is small in size and weighs only 32 grams.

The sensor does not require special installation, it is easy to install it simply on the floor in a bathroom, kitchen, boiler room or any other room with a risk of flooding.

The sensor housing has an IP67 degree of protection and is sealed. The set includes a replaceable battery that lasts up to 16 months.

Q:How does the Leak Sensor work?
A:The Sensor is sensitive to pouring of both detectors located at its bottom with liquid, after which the light and sound alarms are activated. In the case of connection to the Control Gateway, the Sensor transmits a corresponding signal to the Perenio Smart Mobile App.
Q:Where and how can the Leak Sensor be installed?
A:The Sensor shall be installed on a flat horizontal surface close to a possible source of leakage.
Q:How to connect the Leak Sensor in the Mobile App?
A:The Sensor can be connected to the Mobile App in the case of a preactivated Control Gateway only. Login to your User account and add the Sensor as a new device, than select the Control Gateway to which it should be connected. After the Sensor is connected, enter its name and add it to a selected room. See details below.
Q:If the Leak Sensor gets into the water, will it continue to work?
A:Yes, because the Leak Sensor is waterproof, so for some period of time it can be operated in water (provided the Sensor casing is tightly closed). Generally, in the case of flooding, the Sensor will be floating on the water surface.
Q:Will the Leak Sensor work if not connected to the Control Gateway?
A:Yes, the Leak Sensor can be operated autonomously (without connecting to the Control Gateway) and send light and sound alarms in the case of actuation. But in order to receive notifications on a smartphone, it is necessary to connect it to the Control Gateway first.
Q:Is it possible to find out if the sensor is connected?
A:Yes, you can check the status of the sensor in the Perenio Smart App. If the sensor is connected and working, then in the APP you will see the ONLINE status. If the battery of the sensor is discharged or for some reasons there is no connection, the application will display the status that the sensor is OFFLINE.
