What are VOCs?

The air we breathe at home can often be full of volatile substances that are harmful to the body. Many products that we usually have at home, or even the construction materials used to build it, release volatile substances that are toxic or harmful to living beings.

These are the so-called VOCs (Volatile Organic Compounds). They may have different natures and characteristics, which in the short or long term can lead to disorders such as allergies, asthma, etc.

Being gases, it is not always easy to perceive them  in a closed, poorly ventilated environment such as our home. That's why it is important to promptly realize when it's time to open the windows, or turn on the ventilation system in order to purify the air we breathe.

Why buy our sensor?

There are a multitude of sensors on the market capable of detecting harmful compounds such as VOCs, different kinds of gases, air temperature and humidity.

Our sensor detects many parameters useful for monitoring the air quality in our home. In addition to it, thanks to the default integration with DiCE SMART, we will always be able to "see" the quality of the air we are breathing. Air (like electricity) is invisible and VOCs, besides not being visible, are very often odorless (such as carbon monoxide). A sensor connected to DiCE SMART makes everything "visible"; and if we are not at home, thanks to smartphone notifications, we will still know if there is something wrong.

How is it integrated with DiCE SMART?

The DiCEhome app will show us the percentage of VOC in the air at all times, as well as providing a graph with detected temperature and humidity. DiCE SMART, in turn, will signal the critical level with a BLUE flash, and then return to a LIGHT BLUE color when the air has been cleaned because, for example, we opened some windows.

How to connect it to DiCE SMART

To pair the sensor to DiCE SMART, proceed as follows:

  • Open the DiCEhome app on your smartphone.
  • Click on the "+" symbol at the top right and then on "add device".
  • Select the "Air quality" category.
  • Choose a name for the device you are pairing your DiCE with.
  • Choose the house and room where the sensor will be placed or create a new one.
  • Set the sensor on pairing mode (refer to the manufacturer's manual).

How to place and connect it

Where to place it:

  • The sensor is for indoor use and works at a temperature range between 0 and 50 ° C.
  • It should be placed in the room where the VOC concentration is to be measured.
  • Wall installation is recommended, in an accessible area,  to ease maintenance and battery replacement.

  • Open the sensor cover by pressing the button and lifting the top of the lid.

  • Fix the sensor to the wall with double-sided tape or screws.
  • Insert the batteries in accordance with the polarity.
  • Close the lid only when the join procedure is completed and the sensor is correctly associated to the device.


  • When the batteries are inserted, the air quality sensor will start searching (for 15 minutes) for Zigbee networks to connect to.
  • From the DiCEhome app, start the device pairing phase.
  • While the sensor is searching for networks, the LED will flash red.

  • When the LED stops flashing, the sensor has successfully connected to the Zigbee network.
  • If 15 minutes have passed and the procedure has not been completed, press the button inside the sensor to restart the network scan.


The Reset procedure is required when you want to connect the sensor to another Gateway or you want to perform a factory reset to fix issues.

  • Open the sensor cover as shown above.
  • Press and hold the button inside.
  • While holding it down, the red LED will flash once, then two consecutive flashes. It will then make several consecutive flashes.
  • Release the button only when many flashes are made.
  • The LED will flash for a long time to confirm that the device has been reset.
