PROTRONIX NLB-CO2+RH+T-5-SX Battery Sensor with Sigfox User Manual
Combined CO2/RH/T battery sensor with SIGFOX
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 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 via wireless SIGFOX technology
- Maintenance during operation is not required
Description
The measuring of CO2 is based on the principle of infrared radiation
attenuation dependence on the CO2 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.
CO2, RH and temperature outputs are available via SIGFOX
communication. 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-Sigfox-
Communication.

CO2 sensor autocalibration function
Autocalibration compensates for long-term aging of the key components of the sensor. This function is available only when sensor power supply is continuous and uninterrupted. Calibration during operation is not necessary.
LED indication description
-
Turning sensor on:
After turning the sensor on, the measurement period in minutes will be indicated. -
First 10 broadcast:
First 10 broadcasts will be indicated with series of three flashes. -
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.
CAUTION:
It is necessary to avoid severe mechanical shock of the sensor.
