No Contact Thermometer

This is a device I threw together for my wife and I to check our temperature as we didn't have a way to do so. I realize it isn't the prettiest, as I used stuff from the parts bin. I really just threw it together for myself but wanted to share also.

I did choose the screen in particular though. I like the way it displays for its size, and being a rectangle it allowed to share the pixel display with the text display next to it. It also has an sd card slot which I plan to incorporate for saving temperature data.

I just made it in the last couple days given the current situation. It gives a quick peace of mind to us to asses our body temp to assure there is no fever present. It is obviously not definitive, but helpful.

Right now the code is very basic. All it does is map pixels on the screen by the 8x8 grid eye, then if any pixel peaks over 34 C (Red colors) and the button is pushed it will continuously display the current temp of those peaked pixels until the button is released. I origionally did not have the button but ran into a few issues with correct readings. So if any pixels peaked to 34 C or over it displayed the temp of the peaked pixels. But it was always reading and displaying. With the button I could view the display to line up then hold the button and release to get a more accurate reading in a specific area (Like a forehead).

Also the wiring is basic for each component or board. They use hardware ports, nothing special and basic button wiring with a pullup. Here are a few pics:

This was the only thermal sensor I had on hand and thus why my printed box had to be so big. A couple more pictures:

I did print the box but it is also very basic. It worked for me though. I am still working to improve functionality and add to it I just needed to use it for the time being as well.
