- 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.
- It may not function properly.
- It could be permanently damaged.
- It could pose a risk of injury.
- The sensor must not be opened!
- Improper handling such as improper mechanical stress, e.g. dropping the device, may result in damage.
- Dispose of in accordance with local regulations for waste electrical and electronic equipment.
- Contains a lithium battery (UN38.3 compliant) – do not dispose of in fire, do not disassemble or short-circuit.
- The secondary cell is a supercapacitor – do not damage or dispose of improperly.
- Dispose of batteries and rechargeable batteries separately in accordance with the relevant recycling regulations.
- Environmentally friendly disposal by returning to authorized collection points is recommended.
- Do not dispose of in household waste.
- The CO₂ measuring module is particularly sensitive to mechanical stress. A fall, even from a low height, as well as shocks and impacts can damage the device. This can lead to incorrect measurements.

Intended use of the sensor
The solar-powered IoT sensor with CO₂ and humidity detection is ideal for monitoring indoor air quality and environmental conditions. With an integrated CO₂ and humidity sensor, it provides precise data while being energy self-sufficient thanks to its solar panel.
- Optimizing indoor air quality: Continuously measures CO₂ levels to ensure a healthy indoor climate, enabling timely ventilation in high-traffic areas.
- Humidity monitoring: Prevents mold growth and maintains optimal moisture levels for health and plant well-being.
- Energy-efficient operation: Runs on solar power, ideal for areas without power sockets while minimizing energy consumption.
- Customizable settings: Allows users to set CO₂ and humidity thresholds for tailored alarms and notifications.
- Smart building integration: Easily connects to ventilation, heating, and air conditioning systems for efficient control.
- Regulatory compliance: Helps meet air quality standards in public spaces like schools and care facilities.
- Remote monitoring & notifications: Uses LoRaWAN for low-energy data transmission and alerts when critical values are exceeded.

Assembly and preparation
Recommended mounting methods
| Mounting Method | Recommended Accessories |
|---|---|
| Wall Bracket (Screws) | 2x M3 countersunk screws |
| Wall Bracket (Adhesive Strips) | 2x Adhesive strips |
Please note:
- 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 install the sensor at heights above two meters.
- Only install the sensor indoors on a wall in a standard room at a height of 1.50m to 1.80m.
- Install the sensor in a location that receives at least 7 hours of direct sunlight at 400lux per day to ensure optimum energy supply.
- Make sure that the LEDs are on the lower left-hand side when mounting.
Attaching the wall bracket with screws
Please note: Before using this type of installation, make sure that the surface to which the wall bracket is to be screwed is flat and has a base suitable for the material in order to prevent damage to the housing.
Screw the wall bracket into the wall with two M3 countersunk screws as shown in the picture. The snap lock is at the bottom and points away from the wall.
Once the bracket is attached, check that it is secure by gently shaking it. If the bracket is not stable, check the screws and tighten them if necessary.
Once the bracket is securely attached to the wall, you can continue to mount the sensor on the wall bracket as described in the next step
Attaching the wall bracket with adhesive strips
📢 Please note:
- Before using this installation method, make sure that the surface is clean, dry, smooth and adhesive, as an uneven or dusty surface can impair the adhesion of the adhesive strips.
- Avoid mounting on rough, porous or damp surfaces, as this can reduce the adhesive strength and cause the mount to peel off.
- Press the mount firmly for a few seconds after application to ensure an optimum bond between the adhesive strips and the surface.

Stick the wall bracket to the wall in the marked area using the two double-sided adhesive strips, as shown in the picture. The snap lock is at the bottom and points away from the wall.
Once the bracket is attached, check that it is secure by pulling gently on it. Make sure that the adhesive strips adhere completely and that no corners come loose.
Once the bracket is securely attached to the wall, you can continue to mount the sensor on the wall bracket as described in the next step.
Mounting the sensor on the wall bracket

- Insert the sensor into the wall bracket from above until it snaps into the upper bracket
- Tilt the sensor backwards so that it snaps securely into the bracket and the snap lock
- Ensure that the sensor is fully seated in the bracket and is firmly attached
Commissioning the sensor
📢 Please note:
- The housing or electronics may be damaged if knives or other sharp objects are used.
NFC parameterization and position of the NFC tag
- Activation takes place via an NFC app. A smartphone is required for this. The app can be downloaded from the respective app stores. Simply search for “Sentinum LinQs” and download the LinQs app.

- First locate the tag on the sensor and then the reader on your end device. You will find the location of the NFC tag at the following position:

Care and Cleaning
To ensure reliable operation of the sensor and a long service life, it should be maintained regularly. Please observe the following instructions:
-
Regularly remove dust and dirt from the solar panel to ensure optimal energy absorption. Use a soft, clean microfiber cloth for this purpose. In case of stubborn dirt, a slightly damp cloth can be used – however, avoid using cleaning agents or abrasive materials.
-
Clean the housing, especially the ventilation slots of the sensor, with a dry or slightly damp microfiber cloth. Make sure that no moisture enters the device.
-
Perform cleaning regularly, especially in dusty or pollen-rich environments, to ensure the long-term functionality of the sensor.
-
Regularly check that the sensor and its mounting are securely fastened.
-
Do not use cleaning agents containing alcohol or solvents, as these can damage the surface of the sensor.
