Monitor indoor air with clear, continuous readings of CO2, humidity, and temperature. This CO2 Carbon Dioxide Detector provides 24hour realtime monitoring and reports CO2 concentration in PPM within a 400–5000 ppm range so you can spot poor ventilation, protect occupants, and make informed decisions about airflow and HVAC adjustments. Key benefits Know when ventilation is needed: continuous CO2 PPM monitoring helps identify elevated carbon dioxide levels that can signal insufficient fresh air. Maintain comfort and safety: combined humidity and temperature readings give context for air quality and thermal comfort. Simple, focused data: realtime measurements 24 hours a day provide an ongoing view of indoor conditions without guessing. What this device does (functionality) Measures carbon dioxide concentration in the range of 400–5000 ppm and reports results in PPM. Monitors relative humidity and ambient temperature alongside CO2 for a complete picture of indoor air conditions. Provides continuous, 24hour realtime monitoring for ongoing awareness of air quality trends. Key attributes Measurement range: CO2 400–5000 ppm. Outputs: CO2 shown in PPM; includes humidity and temperature readings. Operation: designed for continuous 24hour realtime monitoring. Intended environments: indoor spaces where air quality matters, such as homes, offices, classrooms, and enclosed public spaces. How it helps solve common problems Detects poor ventilation before occupants feel symptoms such as drowsiness or headaches. Supports building management and occupants in optimizing ventilation schedules and HVAC operation. Helps maintain healthier indoor environments by combining CO2 data with humidity and temperature context. Typical use cases Classrooms and offices: Monitor CO2 levels during occupied hours to determine when to increase ventilation or adjust HVAC settings to improve concentration and comfort. Homes and apartments: Track indoor air quality while cooking, during gatherings, or when windows are closed to know when to air out rooms. Small greenhouses and enclosed spaces: Use combined CO2, humidity, and temperature data to assess ventilation and environmental conditions for plants or stored items. Practical tips for use Place the detector at breathing height in the mostused area of the room, away from direct drafts or vents for the most representative readings. Use continuous 24hour monitoring to observe daily patterns and identify times when CO2 concentrations rise consistently. Combine readings with simple actions—opening windows, adjusting HVAC settings, or deploying air cleaners—to improve air quality when CO2 or humidity readings indicate a need. This detector provides straightforward, realtime CO2 PPM readings within a 400–5000 ppm range, together with humidity and temperature monitoring, to help you maintain healthier, more comfortable indoor environments.
