SEN CCS811V1-
1. GENERAL INFORMATION
Dear customer,
Thank you for purchasing our product. In the following, we will show you
which things should be observed during the use.
Should you encounter any unexpected problems, do not hesitate to
contact us.
2. INSTRUCTIONS FOR USE
When using this module, please note that you must perform a so called -
Burn In. This means that for the first 48 hours you will take measure--
ments with the sensor in the mode of your choice. This is because the re-
sistances and sensitivity changes within these first 48 hours, which makes
the measurement results inaccurate within this time.
There is also the so called Run In. This means that within the first 20 mi-- -
nutes aer the sensor has been idle for a long time or aer changing mo-
des, the sensor must stabilize before it can generate accurate data.
The so called modes, which this sensor has, designate the time intervals -
in which measurements are performed. The CCS811 has these modes:
Mode 0 Idle
(no measurements are performed)
Mode 1 IAQ measurement every second
Mode 2 IAQ measurement every 10 seconds
Mode 3 IAQ measurement every 60 seconds
Mode 4 IAQ measurement every 10 ms
(eCO2 and TVOC are not calculated)
In modes 1, 2 and 3, eCO2 and TVOC are calculated each time. Mode 1
reacts fastest to a change, but has a higher operating current. Mode 3
reacts more slowly, but has the lowest operating current on average.
If you change the mode to a slower measuring rate, you should switch to
mode 0 (idle) for at least 10 minutes. This happens, for example, when
you switch from Mode 1 to Mode 3. If you switch to a higher measuring
rate, you do not need to pay any further attention.
Mode 4 is used with an external system. The system receives the raw data
of the sensor to work with it. This allows the measurement rate of one
measurement every 250 ms.
Note: Mode timings are subject to typical 2% tolerance due to accuracy
of internal clock.
