From the Forums: A fever alert – modding the MLX90640 PyBadge Thermal Cam #Fever #Themometer #FromTheForums

From the Adafruit Forums, a post by user Disciple:

This is a software modification for my freshly released thermal camera project. It’s an alternative PyBadge sketch that configures the camera to launch into a fever sensing mode, while preserving all the original camera functions. It consists of two files. One is the alternate source code for the PyBadge using Arduino programming and the Arcada library, the other is a header file containing sound data. Here’s the modded PyBadge code.

The radiant temperature alert threshold is 96.4F, as listed in Comparison of 3 Infrared Thermal Detection Systems and Self-Report for Mass Fever Screening from the CDC. This can be changed if needed, by altering a #define value at the head of the sketch.

Arduino source code is provided. See the post here for more.

Disclaimer: Disciple says “I am not a healthcare professional, and my project is not an approved medical device. I am a hobbyist with a sketch that might prove useful, based on Adafruit’s MLX90640 Breakout, a low-cost radiant temperature sensor. The camera is only as accurate as its sensor, but if that’s adequate for someone’s purpose, I offer this code to make it easier to use.”


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
