Product Description
This product is a multifunctional air quality monitor that detects Carbon dioxide (CO2),Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron-sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock record function. As a scientific air quality detection device, itcombines multiple air sensors with a built-in fan to allow real-time monitoring of Carbon dioxide (CO2), formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.
Considerations
Please read the instructions carefully before using this device. Please let the device work short mins outdoors before use for most accurate results . Please keep the manual handy for quick reference and troubleshooting.
Precautions
Avoid covering the air intake areas during use to avoid inaccurate measurements. Avoid use of solvents to clean the product as residual fumes will skew air quality readings. Avoid water or other liquids near the product to avoid electrical damage. Do not allow unauthorized modification or repair of this product.
Features:
- 4.3″ color liquid crystal display (LCD), 480X270 pixels
- Test variables: Carbon dioxide (CO2)，PM2.5/1.0/10, formaldehyde, TVOC, temperature, humidity
- Large 3000mAh capacity Lithium battery
- On-board fan to draw in ambient air for more accurate real-time results
- 5V Micro USB charging
- Low battery warning Support TUYA Wifi connection
Instructions
Start Up
When you long-press the center power button, the air quality monitor will boot
up. Detector will proceed through its warm-up sequence for about 3 minutes to
allow sensors to preheat and fan to draw in fresh ambient air. This is
necessary for accurate results
- Power ( I/O ) / OK / Menu Button, used to confirm highlighted options or to turn device on/off by pressing for 3 seconds.
- Down / Switch / Decrease Button, used to scroll between interfaces
- Up / Switch / Increase Button, used to scroll between interfaces
- Micro USB charging Port
Switching Among Data Display Formats
Press the up or down buttons to switch among data display formats (figures
1-5) that displays air quality readings in various formats:

Change the Year, Month, Date, Hour, Minute, and Seconds using up/down buttons and confirm each change by pressing center I/O button , It will save each settings Automatic.
It can set Fahrenheit and Celsius. And open / close Alarm.
About Charging
When low battery icon is displayed, the device needs to be charged. Insert the included or another compatible micro USB charging cable into the device. Attach the other end to a USB DC charger (such as a smart phone charger) that outputs DC 5V at >=1000mA. Fully charge for at least 2-3 hours before use. Avoid charging with a USB computer port which only outputs 500mA.
History
