Note before installation
Please make sure the Thingsee GATEWAY is installed before you install
the sensor.
To ensure strong enough signal strength for data delivery, keep the
maximum distance between installed sensors under 20 m.
If the distance between a measuring sensor and the gateway is > 20 m
or if the sensors are separated by a fire door or other thick building
materials, use extra sensors as routers to ensure adequate signal
strength.
General installation instructions
The sensor is for indoor use only.
The environment humidity should be <85 % RH at all time.
The usage temperature range is +5 ºC to +50 ºC, non-condensing
environments only.
Please note that the correct TVOC and CO₂ data are available only aer
the sensor device has conducted baseline calibration for the
environment.
• TVOC sensor conducts baseline calibration for the TVOC levels and
valid data is available aer 24h of continuous use.
• Accurate CO₂ baseline level is set by auto-calibration during the first 8
days of usage. The auto-calibration is based on the outdoor CO₂ level.
CO₂ level in normal air pressure is 400 ppm.
Note: Thingsee AIR requires ‘free of people’ moments in the space,
when the indoor air is fully changed, to set the correct 400 ppm
baseline. This is why places such as schools and oices are good places
to use the sensor, as the baseline can be set during the night.
