Overview
Temp sensing is an open-source printed circuit board by helpfulengineering, from the helpfulengineering/project-temperature-detection repository on GitHub. It is a 2-layer board of 76.2 × 86.4 mm with 26 parts on 23 nets, routed with 166 tracks and 0 vias.
Its parts include 8 resistors, 6 diodes, 2 capacitors and 1 connector.
README
README.mdHardware temperature detection project
Project to build a simple, cheap, open source fever detection device. The aim is to allow symptomatic people to be quickly isolated.
On slack channel #hardware-temperature-detection from helpfulengineering.slack.com
Fast fever detection followed by isolation reduces the spread of infectious diseases.
User Experience
Journey a user goes through to use the system Initial idea is represented in the picture, taking the user from the first interface with the device to the result feedback. It assumes the mirror alignment but does not go into detail about it yet. It also lacks the user experience after the outcome communication.

Questions
How big is the Temp sensing PCB?
It measures 76.2 × 86.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Temp sensing use?
26 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Temp sensing KiCad files?
From the helpfulengineering/project-temperature-detection repository on GitHub, at the commit this page was made from: the board is hardware/PCB/3d_renderings/kiCad files/temp_sensing.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Temp sensing design in my own project?
Its repository states no licence, so its author keeps all rights: ask helpfulengineering before reusing the design.
