About This

• Why do you need a carbon dioxide detector? If you frequently feel groggy, stuffy, or fatigued in a particular indoor environment—especially a bedroom or office—yet are certain that illness or lack of sleep is not the cause, an air monitor equipped with a CO₂ detection function can immediately pinpoint the problem: it is often simply an excessive level of CO₂ resulting from inadequate ventilation. Once you open a window or improve the airflow, that sense of grogginess will typically subside noticeably within 10 to 20 minutes.
• Upgraded Air Quality Detector – Plug & Play Design：This upgraded air quality detector features a more accurate sensor for improved sensitivity. Plug it into any standard US outlet (110V–220V) and use immediately—no standby time. Ideal for bedrooms, RVs, living rooms, basements, hotel rooms, offices, and more.
• High Accuracy & Fast Refresh：Equipped with advanced sensors, it delivers ±5% accuracy for CO2 (400–5000 ppm), ±2.7℉ for temperature (14–122℉), and ±5%RH for humidity (0–95%RH). Real-time readings update every 2 seconds.
• 3-in-1 Air Quality Monitor：The LSENLTY plug-in monitor measures CO2, temperature, and humidity. Includes adjustable threshold settings and manual calibration—reliable and easy to use for homes, greenhouses, offices, and RVs.
• CO2 Threshold Reminder： When CO₂ exceeds 1500 ppm, recommend ventilation—perfect for bedrooms, wine cellars, basements, and other enclosed spaces.
• Manual Calibration：Easily calibrate by placing the unit in a ventilated area and holding the “Sun” button for 5 seconds. A 200-second calibration cycle runs, ending with “Calibration √” on the screen.
