    Product detailed description

    Indoor Humidity Control
    This indoor sensor is designed for direct integration with the Smarwi system and allows you to monitor the relative humidity in a room. When humidity exceeds the set threshold, the sensor sends a signal to Smarwi, which opens the window to improve ventilation.

    The SN130 is a practical solution for areas prone to condensation and mold growth — such as bathrooms, kitchens, toilets, or laundry rooms.

    The sensor also includes a manual activation button — a single press triggers the output for approximately 10 ±1 minutes, allowing you to start ventilation immediately without waiting for the automatic mode.

    What Is the Optimal Relative Humidity?

    Bedrooms and living rooms: 40–60%. Bathrooms: humidity is often temporarily higher, but proper and quick ventilation is essential. Storage rooms and pantries: around 50%. Below 40%: the air is too dry — it can dry out mucous membranes and skin, and irritate the respiratory system. Above 60–65%: condensation may occur on walls, leading to mold growth.

    Safe and Simple Power Supply
    Our sensor can be powered directly from the 12 V DC Smarwi power source.

    • No separate socket required
    • No handling of 230 V mains voltage
    • Easy installation — even for non-professionals

    Both power and signal connections are provided through a single shared cable, ensuring quick and straightforward setup.

    What Does RH Mean?

    Relative Humidity (RH) indicates the amount of moisture present in the air. When the relative humidity reaches 100%, the air can no longer hold additional water, and condensation begins — for example, on windows. At lower values, the air becomes drier.

    Advantages of the Integrated Solution

    • Safe low-voltage connection
    • Humidity measurement with adjustable activation threshold
    • Direct integration with the Smarwi control button
    • Manual ventilation activation via the button on the sensor
    • Discreet design suitable for residential interiors

    How Many Sensors Can Be Connected?

    Only one sensor can be connected to the Smarwi system at a time. Choose the one that best suits your home’s needs — it is not possible to use multiple sensors simultaneously.

    You Can Easily Connect the Sensor Yourself in 5 Steps

    Button Preparation

    Disconnect the power connector from the button. Remove the magnetic cover from the back of the device. Unscrew the four corner screws using a PZ1 Phillips screwdriver, then remove the rear cover of the button.

    Installing the Sensor

    Pass the sensor cable through the opening in the board towards the connector. Connect the sensor connector to the electronic board. The black cable must point outwards from the power connector! Place the board back into the housing so that it fits into its original position.

    Setup and Commissioning

    Set the desired parameters on the sensor (e.g., activation type). After connection and system initialization, your Smarwi will work as before, but with the added option of being activated by the connected sensor.
