Solder the pins to the breakout board of the thermal sensor. Connect the 5 pins of the thermal sensor to the first 5 pins of the GPIO on the Raspberry Pi:

• 5V -> pin 1
• SDA -> pin 3
• SCL -> pin 5
• INT -> pin 7
• GND -> pin 9

Screw the display to the Raspberry Pi and connect the HDMI ports with the bridge plug that came with the display.

Create a nice case to hold everything in place :)

The software has been written en tested on Raspbian Buster.

Go to the GitHub page and follow the instructions in the README file. It gives a detailed description on how to compile and install the software.
