CO2 Sensor

For use with Titon HRV Q Plus Range
ROOM VOC SENSOR

Overview

The Room Sensor CO2 is used to monitor air quality inside buildings and effectively control ventilation (HVAC) systems according to current levels of internal air quality.

The sensor measures concentration of carbon dioxide (CO2) in air. It can be effectively used in offices, classrooms, shopping centres, homes, restaurants, fitness centres, commercial buildings, etc.

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.

The sensor has one analog output for the actual concentration of CO2.

Ventilation, air conditioning and heat recovery units can be directly controlled based on the output signal of the sensor in very efficient way.

The trigger level of CO2 concentration output relay can be set by a rotary element.

Current air quality can be easily checked by three LED indicators. When ambient light is dimmed, the indicators turn off automatically to not disturb you when falling asleep.
