        • Do not use the sensor in safety-critical applications!
        • The sensor is expressly not suitable for monitoring carbon monoxide CO!
        • The sensor is not a smoke detector!
      • The sensor must not be mounted on ceilings or floors
      • Operation of the sensor is only permitted up to a maximum of 2000 meters above sea level.
      • Due to human exposure regulations, a minimum distance of 20 cm must be maintained between the device and persons.

      📢 If the device is installed incorrectly

      • It Couldn't be working properly.
      • It Could permanently damage it.
      • It Could pose a risk of injury.

      📢 Please note:

      • Improper handling, such as improper mechanical stress, such as dropping the device, can lead to damage.

      📢 Please note CO2 sensor:

      • The CO2 measuring module is particularly sensitive to mechanical stress. A fall, even from a low height, as well as bumps and blows can damage the device. This can lead to incorrect measurements.

      Intended use

      The Febris IoT indoor air quality CO₂ sensor is ideal for monitoring the air quality in indoor spaces such as offices, conference rooms, stores or public facilities. It measures the CO₂ content and thus provides important data on air quality and the indoor climate. This information can be used to:

      1. Ensure healthy indoor air: A CO₂ level that is too high can lead to tiredness, difficulty concentrating and discomfort. The sensor enables the CO₂ concentration to be monitored and shows when ventilation or air conditioning should be switched on to ensure good air quality.
      2. Improve energy efficiency: The sensor's data can be used to control ventilation according to demand. Instead of ensuring a constant supply of fresh air (which consumes energy), ventilation can only be activated when it is really necessary. This saves energy and reduces costs.
      3. Creating conditions for high productivity: Good air quality is crucial for concentration and well-being. The sensor helps to ensure optimal conditions, which promotes productivity and general well-being in environments such as offices or classrooms.
      4. Meeting regulatory requirements: Some countries have regulations or recommendations on maximum CO₂ levels in public buildings or workspaces. A CO₂ sensor supports compliance with these standards and transparently shows that measures are being taken to protect the health and comfort of those present.
      5. Enable real-time notifications: With the Ferbis CO2 sensor, measured values can be read out even over long distances. This means that building management can be notified immediately if critical CO₂ values are reached and can intervene if necessary.

      Assembly and preparation

      💡 If the sensor is still easily accessible after installation, first mount the sensor and activate it after installation!

      If the sensor is no longer accessible after installation, activate the sensor first and mount it after activation!

      📢 Please note:

      • Before using this type of installation, make sure that the surface to which the sensor is to be screwed is flat, otherwise the housing may be damaged.
      • Do not insert any objects or body parts into the ventilation slots of the sensor.
      • Do not mount the sensor on the ceiling or floor.
      • Do not mount the sensor at heights of more than two meters.

      The intended mounting location for the sensor is in normal rooms on the wall at a height of 1.50m to 1.80m. Only use the sensor indoors and not outdoors. Make sure that the LEDs are on the lower right-hand side when mounting.

      Wall mounting with screws

      1. Open the case at the snap closure (see arrow) and remove the top. The PCB is screwed into the top.
        Untitled (3)-1
      2. In step two, you will see the bottom of the sensor. For wall mounting you drill holes
        into the concrete wall and attach a dowel. Recommended are M3,5 screws DIN7997. If you attach the sensor to wood, you can screw the screws directly into the wood. Once the dowels are fixed in the wall, thread the provided screws through the holes, as shown in step 2. Alternatively, the other two eyelets in the corner can also be used. Attach the bottom/back wall of the case to the desired object. For other fastening methods DIN7991 screws can also be used.
        Untitled (4)-1
      3. Place the top of the sensor on the attached bottom. Make sure the snap fastener snaps in. Pay attention to the correct mounting direction. The sensor should be mounted as in 3.

      Magnetic mounting

      Permanent magnets can generate strong magnetic fields, which can be dangerous if handled incorrectly. Therefore, observe the following warnings:

      1. Protect hands and fingers: Strong magnets can attract suddenly and pinch fingers or skin. This can lead to painful crushing and injuries. Always keep sufficient distance when handling permanent magnets and wear protective gloves if necessary.
      2. Keep electronic devices away: Magnetic fields can damage electronic devices such as computers, smartphones, credit cards, pacemakers and other sensitive electronics or impair their function. Therefore, always keep a sufficient distance from such devices.
      3. Be aware of the risk of breakage: Many permanent magnets are made of brittle materials (e.g. neodymium), which can break in the event of sudden impacts or high loads. The splinters can be sharp and cause injuries. Therefore, use the magnets carefully and avoid impacts or excessive loads.
      4. Health risks: People with pacemakers or other implanted medical devices should avoid contact with strong magnets, as the magnetic fields may interfere with or disable these devices. If necessary, consult a doctor before use.
      5. Store magnets safely: Keep magnets at a safe distance from each other and from other metallic objects. Sudden attraction can lead to damage, injuries or uncontrollable flying around of the objects.
      6. Danger for children: Permanent magnets are not toys! Small magnets in particular can be life-threatening if swallowed or inhaled and can cause serious internal injuries. Therefore, always keep magnets out of the reach of children.
      7. Avoid heating: Permanent magnets permanently lose their magnetic force at temperatures above their maximum operating temperature (between 80 and 200 °C, depending on the material). Therefore, do not expose magnets to direct heat or open flames.
      1. Open the case at the snap closure (see arrow) and remove the top. The PCB is screwed into the top.
      2. Insert the screws into the holes and connect them to the magnets.Untitled (5)-1
      3. Place the top of the sensor on the attached bottom. Make sure the snap fastener snaps in. Pay attention to the correct mounting direction.Untitled (6)
