4.2.4.3.3 CO2 sensor

General

A CO

2

sensor can be useful in all cases where CO

2

develops in enclosed spaces. In some

countries, a CO

2

sensor is already compulsory in schools. This CO

2

sensor is designed exactly

for this purpose and can also be used for controlling automatic room ventilation available on
site.
The power supply of the CO

2

sensor is supplied via the bus.

Functional description

After connecting the bus voltage of after bus voltage return, the CO

2

sensor starts measuring

the CO

2

concentration of the room air. The measured values are transmitted to the bus. If

adjustable limiting values are exceeded within the range from 0...2000 ppm, specific actions can
be triggered (e.g. room ventilation). The 4 limiting values are preset as follows: 400 ppm for very
good air quality, 800 ppm for good air quality, 1,200 ppm for medium air quality and 1,600 ppm
for poor air quality.

CO

2

sensor module

The integrated CO

2

sensor module is responsible for measuring the CO

2

. It is maintenance-free

due to the automatic calibration method (dual beam measuring cell). It has excellent long-term
stability.

i

After switch-on, the CO

2

sensor module requires a warm-up period of up to 5 minutes, until

normal operation is reached.
The automatic calibration method is only available in the case of permanent bus voltage
and after 24 hours for the first time.

Sensor data of the CO

2

sensor module

-

Measuring range... 0..2000 ppm

-

Accuracy (when 25 °C and 1013 mbar)... <± 50 ppm (+2% of the measured value)

-

Temperature dependency... typ. 2 ppm / K (0 ... 50 °C)

-

Response time... <5 min

Air pressure

The measured value of the CO

2

sensor is air pressure dependent. As the air pressure

increases, so does the measured value. The parameter "Height of location above sea level" is
provided in order to compensate for this dependency. The current height of the location (in
meters above sea level) can be parameterised using this parameter. The installation height is
adjusted in 1m increments.
