Product detailed description
Indoor Air Quality Control
This room sensor is designed and optimized for full integration with the Smarwi system for automated ventilation and window control. It is equipped with a sensor that monitors concentrations of gases related to indoor air quality. When preset thresholds are exceeded, the sensor automatically sends a signal to the Smarwi controller, which opens the window to improve ventilation.
The sensor features an auto-calibration function that continuously compensates for measurement deviations and sensor aging over time, ensuring long-term accuracy and reliability.
It 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.
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 hassle-free setup.


How Many Sensors Can Be Connected?
Only one sensor can be connected to the Smarwi system at a time. Choose the one that best fits your home’s needs — it is not possible to use multiple sensors simultaneously.Advantages of the Integrated Solution
- Safe low-voltage connection
- Automatic monitoring of indoor air quality levels
- Direct integration with the Smarwi control button
- Manual ventilation activation via the button on the sensor
- Discreet design suitable for residential interiors


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.
Removing the Original Board
Remove the electronic board with the button and connected cable. Carefully disconnect the rectangular cable from the connector.
Sensor Installation
Feed the sensor cable through the opening in the board toward the connector. Connect the sensor’s connector to the electronic board — make sure the black cable faces outward from the power connector. Insert the board back into the housing, ensuring it fits securely into its original position.
Finishing the Installation
Reattach the back cover to the button. Tighten the four screws. Place the magnetic cover back on, and reconnect the power connector.
Setup and Commissioning
Set the desired parameters on the sensor (e.g., activation type). After connecting and initializing the system, your Smarwi will function just as before — with the added benefit of being activated by the connected sensor.Technical Specifications
