SMART AIR QP Lite Air Quality Monitor User Guide

Table of Contents

The QP Lite comes with a USB-C charging cable, you will need to add your own 5v/1A power adapter plug to charge from a socket
Switching on

The first time you switch it on, plug into a power adapter and charge – ideally overnight (ensure the temperature isn’t above 40 degrees when charging)
From the screensaver – long press the on/off button at the back

Switching off

Download the Qingping+ app onto your phone (you need the app to change the device settings). Open the Qingping+ app, select the + button
o Find and select the QP Lite monitor
o Select ‘Yes’ for Bluetooth
o Select QP Protocol
Press and hold the concave bar at the top of your monitor for about 8 seconds until a large Wi-Fi icon appears on the screen
Assuming you are connected to Wi-Fi on your phone, the app should ask you to name this monitor and then proceed to add it to the dashboard (you can add as many devices as you like to this dashboard)
Click on the settings using the ‘tools’ icon on the top right:
o Check the ‘Firmware Update’ to see if you have the latest version of the software. If not, update (note that the firmware is regularly updated so it is good practice to check you always have the latest version)
o Reset the CO2 sensors – you will need to place the device outside for around 12 minutes as it will use the more consistent outdoor level as a baseline
You can also use the settings to set up your temperature unit (F or C) and other screen saver options

The Lite will show you one screen at a time – swipe on top to change the screen to see the other measurements
There are 5 screens in total, it will stay on the last screen you looked at
The battery life should last around 6-7 hours, but you can use a screen saver and auto-off to preserve the battery (see tips below), or you can switch it off at the back
Each screen has a line of light at the top, this is color coded to green/amber/red so you can see immediately the alert levels

Depending on the changes you are making via the settings on the app, you may need to ensure the device is on
The screen saver protects the screen but if you want a reading all the time, select ‘bounce’
If the device is switching off, please check the ‘auto-off while using battery’ on the app. You can set this to ‘never’ if you want all-day readings
If you switch on ‘auto-off while using battery’ or ‘screen auto-off during night’ to preserve the battery, you won’t get historical readings for this time. If you want to have permanent historical readings, please keep your monitor always plugged in
If you have two different air quality monitors and are concerned about the fluctuations in CO2 levels between the two, don’t worry. Outdoor levels are around 350 – 450 ppm so the discrepancy could be due to when and where you calibrated the sensors when you first set it up
