NLB-CO2+RH+T-5-IQRF | Combined CO2/RH/T battery sensor with IQRF
The sensor is used to continuously monitor air quality inside buildings and
then control ventilation (HVAC) systems according to current levels of air
internal air quality. The sensor measures the concentration of carbon dioxide
(CO2), relative humidity (RH), and temperature (T).
It can be effectively used in offices, classrooms, shopping centers, homes,
restaurants, fitness centers, commercial buildings, etc.
- measures CO2, RH, and temperature
- communication over IQRF network
- maintenance during operation is not required
Description
The measuring of CO is based on the principle of infrared radiation
attenuation dependence on the CO, concentration in the air (NDIR). Built-in
auto-calibration function ensures very good long-term stability. Measurement
of relative humidity is based on the principle of capacitive polymer sensor.
CO,, RH and temperature outputs are available via the IQRF interface. The
sensor can efficiently manage ventilation and heat recovery units, based on
current air quality.
The current battery state can easily be determined by looking at the LED
indicator. For detailed information about IQRF, use the document NLB-IQRF-
Communication. For information on the communication protocol, use the document
NLB-Modbus-Communication.
Explanation of abbreviations and technical terms can be found on our website
in the Glossary section.

CO2 sensor autocalibration function
Autocalibration compensates for the long-term aging of the key components
of the sensor. This function is available only when the sensor power supply is
continuous and uninterrupted. Calibration during operation is not necessary.
LED indication description
Each item of signalization can be deactivated over IQRF communication.
Turning sensor on:
After turning the sensor on, the measurement period in minutes will be
indicated.
First 10 broadcasts:
The first 10 broadcasts will be indicated with a series Battery under 20%:
If there is less than 20% energy remaining, LED will indicate this state with
flashing once an hour, after broadcasting the data.
Battery under 5%:
If there is less than 5% energy remaining, LED will indicate this state with
flash after every data broadcast.
Bonding button PAIR
Button is located on the electronics board. Detailed instructions on how to
proceed with bonding and unbinding is shown in document NLB-IQRFCommunication.
The RESET button can be used to restart the sensor.
CAUTION:
It is necessary to avoid the severe mechanical shock of the sensor.
