Air Quality Sensors

Indoor air quality affects comfort, well-being, and productivity. In this section you’ll find smart sensors and monitors to track the main indoor air parameters, such as CO₂, particulate matter (PM2.5/PM10) and, on some models, also VOC/TVOC and formaldehyde (HCHO). Measuring these values helps you know when to air out the room, when to turn on an air purifier, or how to best manage ventilation and heating. Many devices offer displays, notifications, data history, and integrations with your smart home (for example via apps or compatible standards). To choose the right model, consider which parameters you want to monitor (CO₂ or particulate, or multi-parameter sensors), the presence of alarms/thresholds, connectivity, and integrations. If you want to actively improve the environment, you can pair these sensors with air treatment solutions and create useful automations (e.g., turning on the purifier or a ventilation alert).
