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 VOCLESS 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 VOCLESS sensor is maintenance free except replacement of the batteries.
Calibration:
Factory calibrates the VOCLESS sensor when it is produced. The VOCLESS sensor is maintenance-free in indoor
environments due to the Nanosensorics integrated intelligent computational algorithms (AI) and Automatic
Correction and index algorithms. Those algorithms provide long term sensor measurement reliability and no
additional manual calibration is needed during lifetime of the device.
VOC measurement description:
Nanosensorics integrated advanced intelligent (AI) computational algorithm measures and evaluates
Volatile Organic Compounds (VOC) levels and automatically adapts its output to any indoor environment and maps
all VOC events to a VOC Index scale ranging from 1 to 500 VOC Index points (Figure below). The value 100 refers to
the average indoor gas composition over the past 24 h. While values between 100 and 500 indicate a deterioration,
values between 1 and 100 inform about improvement of the air quality. If the VOC levels are above 100 index, it is
recommended to ventilate, if the levels are above 250 index, heavy ventilation and purification of indoor air is
mandatory as soon as possible.
