Thermal Camera

This Thermal Camera was inspired by the DIY Mini Thermal Camera from Adafruit, based on the 8 x 8 infrared grid array sensor amg8833. This version is based on the cheap ESP8266 and an ILI9341 touch screen. Two software versions are available, one is based to the Adafruit example, the second and more advanced regarding interpolation, is based on the code of Kris Kasprzak. Both were slightly enhanced to provide a portrait screen orientation, a thermal scale, a touch screen autoscale function, a lipo monitoring and a temperature measurement in the center.

By exchanging the micro controller, the total cost of hardware was reduced to around 55€. Since the design was kept simple and the code was available, this was a nice little weekend project.

As AliExpress offers a smaller version of the amg8833 pcb, Manuauto designed a small adapter to fit the housing. The adapter is available at https://www.thingiverse.com/thing:3066479. Link the sensor pcb: https://de.aliexpress.com/item/AMG8833-IR-8-8-W-rmebildkamera-Array-Temperatur-Sensor-Modul-8x8-Infrarot-Kamera-Sensor/32867572849.html

The user Manuauto added support of the SD card to save images by pressing a button, the code can be found at github: https://github.com/wilhelmzeuschner/arduino_thermal_camera_with_sd_and_img_processing I will try to add the slot for the SD card as soon as possible

UPDATE / 12.08.2018

Due to the change from 22.02.2018, the pin assignment was inconsistent. Mapping was updated at sourcecode, table and graphic. Data type of MINTEMP&MAXTEMP was changed to float, this should fix the compile error which was observed by some users

UPDATE / 28.03.2018

There was a mistake in the connection table, SDA and SCL were swapped, the pinning is corrected. The hardware will not be harmed, it just would not work.
Added Fritzing sketch

UPDATE / 22.02.2018

For a new display driver which allows a higher framerate, the pin mapping was updated as well as the arduino sketches. Pin D3 and D8 have been swapped. Faster display driver included for the ESP8266 Wemos D1 Mini or Node MCU. Fixed battery display
