9 September 2020  |   News

Thank you for your trust and purchase of LookO2 personal air quality sensor

We hope that the device will meet your expectations – please read the manual and contact us if you have any questions.

To turn on the device, you need the dedicated power supply (12V 1.4A) included with LookO2.

Before starting the sensor configuration, please prepare the sensor’s GPS coordinates, i.e. the longitude and latitude where the sensor will be installed. Thanks to this, the sensor will appear on the looko2 map and in proprietary and partner applications. This data can be supplemented later, but it requires a device reset and the configuration from scratch.

How to easily find GPS coordinates:

Items can be downloaded from the GOOGLE MAPS website by clicking on the street and copy the displayed values:

Everything is ready ?

Let’s start!

Plug the power adapter into the power supply and plug into the LookO2 device. The device will flash green several times (which means it is turning on) and start blinking white – informing us that it is waiting for configuration via WiFi. (In the gray version of the housing, the light notifications are not visible.)

When the device flashes white, it indicates that it is factory reset and ready for WiFi setup. Open the WiFi settings on your computer and search for the network named LOOKO2 and then connect to it.
