During the COVID-19 crisis, it can be valuable to know if you, or persons close to you, have a fever or not. Having a fever can be one of the symptoms of being infected with the Corona virus. So I came up with designing a device around a far infrared Thermal Sensor, a Raspberry Pi and a small TFT display. The face skin temperature of a healthy human being is in the range of 32 to 34 degrees. Skin temperatures higher than that might indicate a fever. Since the package is small, it is easy to place it e.g. next to a door entrance.

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 :)

Installing the software
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.
I know there are days when my face feels hot and flushed, typically when I have allergy symptoms. I wonder what surface temperature I'd be showing on days like that.
There are some very useful and interesting things I read in this post very similar to Vanity Medical spa as you can see here.
