NLB-CO2+RH+T-5-IQRF | Combined CO2/RH/T battery sensor with IQRF

PROTRONIX NLB CO2 RH T 5 IQRF 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.PROTRONIX NLB CO2 RH T 5
