When opening the package, please confirm whether the air quality monitor is in good condition and the accessories are complete. This product comes with a battery. Please charge it for 5 minutes before using it for the first time, and then press and hold the multi-function button to turn it on.

The device display and components include:

Multi-Function Button: Used for power and switching display content.

Temperature and Humidity Sensor: Measures ambient temperature and humidity.

Type-C Charging Port: For charging and power supply.

Auto Brightness Sensing Area (Do not block): Adjusts screen brightness automatically.

Grade Indicator: Shows the air quality level (e.g., Good).

WIFI Indicator: Shows the WiFi connection status.

Alarm/Sound Indicator: Indicates if an alarm is active.

Battery Indicator: Shows the battery level.

CO2 Concentration value: Displays the Carbon Dioxide level.

PM2.5 Concentration value: Displays the PM2.5 level.

HCHO or PM1.0 Concentration value: Displays Formaldehyde or PM1.0 level.

TVOC or PM10 Concentration value: Displays Total Volatile Organic Compounds or PM10 level.

Temperature: Displays the current temperature.

Humidity: Displays the current humidity.

Power on: In the power off state, press and hold the “multi-function button” for 2 seconds. The buzzer will sound “beep”, and the current parameters will be displayed on the screen.

Power off: In the power on state, long press the “multi-function button” to power off.

Switching the display content: When powered on, press the “multi-function button” once to switch the display between HCHO & TVOC and PM1.0 & PM10.

Waking the screen: This product has a distance sensor. In the dormant state (dormancy after 30 seconds without sensing, which can be closed in the APP), you can approach the product directly or wave in front of it to wake up the screen.

There are two calibration methods:

Manual calibration:

1. Turn on the device and place it in an environment with a CO2 concentration of about 400PPM (outside or by a window for convection ventilation) for 5-10 minutes.

2. Press the “multi-function button” 3 times in quick succession.

3. After a few seconds, the device will automatically shut down to complete the manual calibration.

4. Restart the device to use normally.

Automatic calibration:

After 24 hours of power on, the sensor will set the lowest CO2 value within those 24 hours as the zero value. Please ensure that there is some ventilation time within the 24 hours.

The general indicators are:

Green: indicates Good

Orange: indicates Poor (If one of them reaches Poor, an alarm will sound)

Red: indicates Unhealthy

The specific ranges for each substance are:

CO2:

Green: 0 – 1000ppm

Orange: 1000 – 2000ppm

Red: Above 2000ppm

PM1.0:

Green: 0 – 25µg/m³

Orange: 25 – 75µg/m³

Red: Above 75µg/m³

PM2.5:

Green: 0 – 25µg/m³

Orange: 25 – 75µg/m³

Red: Above 75µg/m³

PM10:

Green: 0 – 50µg/m³

Orange: 50 – 150µg/m³

Red: Above 150µg/m³

TVOC:

Green: 0 – 0.5mg/m³

Orange: 0.5 – 1mg/m³

Red: Above 1mg/m³

HCHO:

Green: 0 – 0.1mg/m³

Orange: 0.1 – 0.15mg/m³

Red: Above 0.15mg/m³

A. Scan the QR code provided in the manual to download and install the app.

B. By default, the device will enter the pairing state after it turns on for the first time, and the WiFi icon will flash.

C. Open the app, register an account, and log in.

D. Click “Add Device” or the “+” icon at the upper right corner to add the device. A connection box will pop up; click “Add” to start pairing. You can also add the device manually if it is not discovered automatically.

Click the icon of the connected device on the App home page to view specific data. Click the value you want to view, and you can then check the historical data of that value in a graph.

To enter the settings, slide the screen to the bottom and click on “Set”. Adjustable options are: Alarm value (for PM2.5, CO2), alarm sound, temperature unit, and screen off settings.

There are two ways to reset the WiFi:

1. Reset via App:

Click the icon at the upper right corner of the device’s page in the app to enter the settings interface. Click “Remove Device”, and then re-enter the pairing status after removing the device.

2. Reset on Device:

In the off state, press and hold the multi-function button for 8 seconds. During this period, the screen will light up and emit a first “tick”. Continue holding until the buzzer sounds “ticks” for the second time, the WiFi icon flashes, and the device enters the pairing state. Then release the button.

1. Since the product uses high-precision sensors and components, please keep the product in a dry environment without direct sunlight.

2. Before first use, after purchasing or changing environment, place it in a fresh air ventilated environment to either calibrate it manually or automatically for about 24 hours in the open air. The device needs to measure the open air at least once per 24h for representative results.

3. Do not block the air inlet when in use.

4. The product is not waterproof; do not immerse or splash water or other liquids on it.

5. Do not insert sharp, flammable or metal objects into the air inlet of the monitor; otherwise, it may cause electric shock and burn.

6. This product has an automatic brightness adjustment function; it will adjust the screen brightness according to the ambient brightness. Please do not block the brightness sensing area, as it will cause the screen brightness to be too low.

7. Please use the USB-C cable for power supply when the product is used for a long time. The battery is only suitable for temporary use.

8. Beware of the product being dropped or severely impacted, which may cause the product to fail to work properly.

9. The detection of this product is qualitative rather than quantitative; there will be some deviation in the measurement value. Please refer to the accuracy range for details.

Note: Do not hold the product close to your face, as your breath will affect the CO2 detection.

WiFi icon is flashing: It is in the pairing state and needs to be paired with the smart phone and the wireless router.

WiFi icon is always on: Normal connection status.

WiFi icon flashes slowly: It has been paired with the smartphone once, but the current network is abnormal (for example, the paired router is not turned on), and the network needs to be restored or paired again.

No WiFi icon: The product is not a WiFi version, or the WiFi module is damaged.

Re-pairing is required if the network is changed.

A device can only be paired with a smart phone and a router.

A smart phone can be paired with multiple devices (up to 200 devices).
