Key benefits Get fast, stable readings of indoor air quality so you can act quickly when ventilation is needed. See CO2, temperature and humidity in one device to better understand and manage comfort and air safety. Simple color-coded display makes it easy to interpret measurements at a glance without technical knowledge. Rechargeable, wireless operation lets you move the detector where you need it without cords. What this device does Continuously monitors carbon dioxide concentration, ambient temperature and humidity. Provides stable, accurate measurement values with a real-time refresh rate of 1 second per reading for faster detection of changing conditions. Uses a clear color screen that changes color to indicate air quality levels, helping you notice problems immediately. Performance and power Fast measurement update: 1 second/time real-time refresh for rapid detection. Stable and accurate readings to monitor air quality trends and support timely ventilation decisions. Built-in 1200 mAh rechargeable battery with Type-C charging for convenient recharging. Wireless operation and standby time of 240–360 minutes (approx. 4–6 hours) for flexible placement and use. Ease of use and compatibility Smart, easy-to-read color screen reduces interpretation time; ideal for non-technical users. Type-C charging interface ensures compatibility with common chargers and power banks. Wireless detection means no tethering to a power outlet during use. Practical applications Home: Place in living rooms, bedrooms or kitchens to monitor CO2 levels and indoor comfort (temperature and humidity), helping improve sleep, ventilation and overall comfort. Office or classroom: Track air quality during the workday or lessons to reduce drowsiness and maintain a healthier indoor environment. Travel and temporary spaces: Use in rental apartments, hotel rooms or meeting rooms to quickly assess ventilation and comfort before extended occupancy. What makes it stand out Combines three environmental parameters (CO2, temperature, humidity) into one compact, portable unit. Fast 1-second refresh rate and stable measurements give confident, timely information. Color-coded display provides immediate, actionable feedback without needing to interpret numbers. Tips for use Place the detector at breathing height in the area you occupy for the most relevant readings. Recharge via the Type-C port before extended use; expect wireless operation for several hours on a full charge. Pay attention to color changes on the screen to identify when to ventilate the space or adjust HVAC settings.
