Raw Data 

The raw temperature data points in Fahrenheit are logged every hour to text files on the 
SDCARD named “sensor1.txt” and “sensor2.txt”.  To read or parse the files move the SDCARD 
to your computer and view them using your favorite text editor.  Temp values are logged every 
hour, with T+0 (the latest values) at the bottom of the file.  

The VOC values are a bit di

erent.  The values in the graph are capped at 200 ppb, but the 

actual RAW sensor values are captured on the SDCARD.  Again, refer to the documentation for 
the SGP30 for more information.

Wifi/Octoprint 

The values for temperature and air quality can optionally be displayed in real-time in Octoprint.  
If you want to run Octoprint, that’s beyond the scope of this manual, but there are plenty of 
online resources on how to hook your 3D printer to Octoprint.  These instructions will focus on 
connecting this device to an existing Octoprint installation.

The first step is configuring the device for Wifi by following the instructions on the touchscreen.  
You’ll need to use your mobile phone, but it's pretty straightforward.

Once Wifi is configured, the next step is to configure Octoprint.  The 3DUPfitters plugin 
depends on another plugin called Plotly.   Please search for this plugin and add it to the Plugin 
Manager.
