User manual NLII-CO2+RH+T-5-SX | Combined CO2/RH/T sensor with SIGFOX Room sensor NLII-CO2 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 2x analog voltage/current output SIGFOX wireless communication 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 autocalibration function ensures very good long term stability. Measurement of the relative humidity is based on the principle of capacitive polymer sensor. The sensor has built-in two separate analog outputs one for the actual concentration of CO2 and the other for the current relative humidity. Temperature output is available by Sigfox communication. So the sensor efficiently manages ventilation and heat recovery units, based on current room air quality. The current air quality can easily be determined by looking at the three LED indicators. The eco level means good indoor air quality necessary to achieve a sense of well-being and at the same time optimal energy costs for heating, ventilation or air conditioning. For detailed information on the communication protocol, use the document NLII-SigfoxCommunication. Explanation of abbreviations and technical terms can be found on our website in the Glossary section.

This function is available only when sensor power supply is continuous and uninterrupted. Calibration during operation is not necessary. Selected analog output values versus actual CO2 concentration Selected analog output values versus actual RH Typical RH measurement accuracy at 25 °C LED indication description White LED lights: Less than 600 ppm CO2 or less than 40 % RH. (according to the quantity selected for indication) maintaining low concentrations of CO2 is not cost-effective - slightly increased concentration does not cause any health complications low concentrations of RH. Too dry air feels cooler as compared to equally hot but more humid air risk of drying of the mucous membranes - respiratory problems Green LED lights: More than or equal to 600 ppm CO2 or 40 % RH, less than or equal to 1200 ppm CO2 or 60 % RH. (according to the quantity selected for indication) optimal balance of air quality and energy efficiency of ventilation and air conditioning optimal relative humidity for humans Yellow LED lights: More than 1200 ppm CO2 or more than 60 % RH. (according to the quantity selected for indication) higher concentration of CO2 - further increase of CO2 concentrations above this level can cause fatigue, restlessness, headache too high humidity - the risk of mold growth and associated health complications Protronix s.r.o., Pardubická 177, Chrudim 537 01, Czech Republic www.protronix.cz/en/ www.careforair.eu/en/ um-nlii-co2+rh+t-5-sx-en-v3-201026.docx 2/6 User manual NLII-CO2+RH+T-5-SX | Combined CO2/RH/T sensor with SIGFOX Sensor start after power on CAUTION: All three LEDs flash simultaneously until the first readings are available, but no longer than 10 seconds.
