Product description
Why no battery? Six sensors run at once – CO₂, TVOC, HCHO, Temp, Humidity, AQI. Their combined power draw drains batteries too quickly. USB power ensures stable, uninterrupted performance. Plug into any USB port and monitor 24/7 without worrying about charging or shutdowns.
Why We Need Air Quality Monitor? 
Indoor air is invisible but constantly changing. CO₂, HCHO, TVOC, humidity, and other factors can affect your environment. An air quality monitor helps you see changes and take action.
Easy to Use
Short press power button: Switch between ℃ and ℉; Short press M button: Switch between mg/m³ and ppm;
Press any button to pause the alarm for 1 min. Long press M button: turn off the alarm sound
Can it detect smoke or other gases?
This DA10 (6-in-1 Air Quality Monitor) is specifically designed for indoor air safety, tracking CO2, HCHO (Formaldehyde), TVOC, AQI, Temperature, and Humidity.
When will the alarm sound and how can I turn it off?
The alarm activates only when both key air quality readings reach the red level. Press any button to stop the sound immediately. Monitoring continues in real time after the alarm is silenced.
Why does it take about 1 minute to start?
DA10 uses high-sensitivity air quality sensors that require a short warm-up and calibration period before operation. This 60-second process ensures accurate and stable real-time readings rather than instant but unreliable data.
Should I keep it plugged in all the time? No battery?
Yes, it’s powered by usb. You need to keep it plugged in all the time.
Can it switch between temp units?
Yes, the DA10 Air Quality Monitor can switch between temperature units. With a single short press (On/Off button), you can toggle between °C and °F. It also lets you switch between mg/m³ and ppb units for pollutant measurements.
【USB-Powered for True Real-Time 1-Second Monitoring】 The DA10 is designed for continuous USB-powered operation, refreshing measurement data approximately every 1 second for responsive, real-time monitoring. Unlike monitors designed around longer refresh intervals, the DA10 continuously updates readings so you can see changes in your indoor air more quickly. The device does not have a built-in battery and must remain connected to USB power during use.
【6-in-1 Air Quality Monitoring with Color Alerts】 Monitor CO₂, HCHO, TVOC, temperature, humidity, and overall air quality in real time. The clear display uses intuitive Green/Yellow/Red color indicators to provide an easy visual reference as pollutant levels change, helping you quickly understand your indoor air conditions.
【Professional Sensors with 59-Second Warm-Up】 Equipped with professional-grade sensors, the DA10 measures CO₂ (400–5000 ppm), TVOC (0–2.0 mg/m³), and HCHO (0–1.0 mg/m³). After powering on, allow approximately 59 seconds for sensor warm-up and stabilization before relying on the readings. Temporary fluctuations during warm-up are normal.
【Smart Alarm with 1-Minute Pause & Mute Function】 When pollutant levels reach the preset alert threshold, the DA10 provides visual and audible alerts to draw your attention to changing air conditions. When the alarm sounds, press any button to pause the alarm for 1 minute. To turn off the alarm sound, press and hold the M button.
【Easy Unit Switching & Proper Placement】 Press the ON/OFF button to switch between °C and °F, and press the M button to switch between mg/m³ and ppm where supported. For best results, place the monitor in an open area with unobstructed airflow, away from direct airflow, strong odors, or other conditions that may affect measurements. Its compact 3.15 × 3.94 × 1.38 in (80 × 100 × 35 mm) design fits easily on nightstands, desks, shelves, and counters.
