Push button and LED indicator description:
Once batteries are installed or reset button will be pushed in the sensor, it will automatically
attempt to connect to the LoRaWAN network and the LED indicator will start to be blinking /
flashing for 15 seconds.
In case of the successful connection to the LoRaWAN network LED indicator will stay on for 3
seconds and LED indicator will stop flashing and go dark. This means sensor successfully connected
to the LoRaWAN network.
If the sensor will not connect on the initial try, it will attempt to connect to the LoRaWAN network
after 10 seconds, then after 60 seconds, then after 10 minutes, then after 1 hour, then after 24
hours till successful connection to the LoRaWAN network.
The sensor will restart by pressing the button on the sensor and it will attempt instantly to connect
the LoRaWAN network.
The CARBONLESS sensor has to be installed reliably and with appropriate screws. The sensor must not be
placed near any air vents windows, door openings where the constant fresh air flow is possible. The sensor is not
suitable to be installed for the outdoor locations. The sensor cannot be stored at dusty or dirty areas with excess
operation and storage temperature. The sensor is not washable, paintable. The open holes of the case must not be
blocked, glued with any material. Do not throw the battery into a fire to prevent the battery from exploding.
Damaged batteries may also explode. All of the above suggestions apply equally to your device, battery and
accessories.
The CARBONLESS sensor is maintenance free except replacement of the batteries.
Calibration
Factory calibrates the CARBONLESS sensor when it is produced. The CARBONLESS sensor is maintenance-free in
normal indoor environments due to the Nanosensorics integrated intelligent computational algorithms (AI) and
Automatic Baseline Correction (ABC) technology. Normal environment is where there is no constant round the
clock occupancy or constant high levels of CO2.
If there is a need for manual calibration, these instructions must be followed: After installing the batteries in the
sensor, bring the device outside in the fresh air for 10 minutes. The CO2 sensor will then use the CO2 levels from
fresh air to compare with the CO2 levels indoors to give accurate values.
Nanosensorics (AI) and (ABC) intelligent algorithms constantly tracking of the sensor’s lowest reading value over a
predetermined time interval, and slowly corrects for any long-term drift detected as compared to the expected
fresh air value of 400 ppm of CO2.
In normal indoor environment, the CO2 level drops to nearly outside air some time during a week. By sampling the
values for a period of 7 days and then comparing the lowest value with the 400 point, the CARBONLESS sensor is
able to understand if it needs to adjust the zero point. This algorithm takes advantage of the fact that the CO2 level
stabilizes in buildings when unoccupied.
