This is a Handheld Contactless IR Thermal Camera powered by a Raspberry Pi Zero W.
Images are captured by the Adafruit IR Thermal Camera Breakout.
This sensor from Panasonic is an 8x8 array of IR thermal sensors.
Images are displayed on an Adafruit PiTFT Plus 480x320 3.5" TFT+Touchscreen for Raspberry Pi.
Any Raspberry Pi and Adafruit PiTFT Display can be used for this project.
The Adafruit IR Thermal Camera Breakout is also fully compatable with most linux SBC and microcontrollers.
For those who wish to replicate this project, in the event the Adafruit breakout is not available,
the MAXREFDES131# from Maxim Integrated Products also utilizes the Panasonic chip and can be used as substitute (might require some config).
The Adafruit IR Thermal Camera has been soldered to the i2c bus on the Pi Zero W
The Adafruit PowerBoost 1000c and 2500 mAh lipo battery supply power to the 5V VIN pinout on the display.
Layers of duct, electrical, and polyimide (kapton) tapes have been used to secure and insulate components.

this sensor is accurate enough to detect minute fluctuations of heat. For this demo, the code is set to display any temp over 36°C (96.8°F) in red.
This would normally be set to 38°C (100.4°F) in order to detect above average body temp. Average human body temp is 37°C (98.6°F)
The following images were previously captured

Image captured without shirt. Notice how the fabric masks some of the heat signature.
