Collection: Indoor Air Quality (IAQ) and Combo Sensors
Indoor Air Quality (IAQ) affects health and productivity, with pollutants like mold and VOCs causing issues, while good ventilation improves well-being, and sensors help manage these conditions by signaling systems to adjust for cleaner air, reducing headaches and fatigue. Combo Sensors measure room levels of varying conditions. Many models include temperature and relative humidity, while others incorporate these with air quality sensors for gases (CO2, CO, NO2) and/or particulate matter.
