VOC Sensor
Overview
The Room VOC sensor is used to continuously monitor indoor air quality and for effective control of ventilation (HVAC) systems according to current air quality.
The sensor monitors the concentration of VOC – Volatile Organic Compounds in air. It can be effectively used in restaurants, kitchens, fitness centres, toilets, changing rooms, gyms, offices, commercial buildings, schools, households etc.
Built-in advanced VOC sensor is sensitive to volatile organic compounds typically contained in the exhausted air – gaseous metabolic products of human bodies and other gaseous pollutants such as formaldehyde, disinfectant vapours, cooking vapours, fumes from paints, varnishes, adhesives, detergents, cigarette smoke etc. that the CO2 sensor does not detect.
There is the possibility to select eCO2 (estimated CO2) measurement mode. In this mode the sensor uses special algorithm to estimate CO2 concentration based on the assumption that the TVOC produced by human metabolism is proportional to the exhaled CO2. The analogue voltage output of the sensor is adjusted as equivalent to a standard CO2 sensor in range of 400–2000 ppm of estimated CO2.
The trigger level of output relay can be set by a rotary element. Ventilation and heat recovery units can be directly controlled based on the output signal of sensor in the most efficient way.
Current air quality can be easily checked by three LED indicators.
