project progress

Since the time for this event is relatively tight, and Renesas MCU and thermal imaging functions are things I have never been exposed to before, it will inevitably take time to get into the pits. Here is a rush to complete the core temperature imaging function before the event ends. After coming out, you will first participate in the closing session, and you will continue to improve the functions and program algorithms later. --May 9, 2022--
The current effect is as shown below:

Preface

1. Thank you for the strong support of Lichuang Ecology, @利竞技 Mall @利盈PCB/SMT @利盈EDA @利创Open Source Community @利创panel manufacturing @利竞技3D printing
2. Thank you for the strong support of Renesas, @瑞SaRA MCU Ecological Studio
3. Special thanks to @micespring, the source of inspiration for this project! Here is the link to the big guy’s LiChuang open source project: https://oshwhub.com/micespring/AMG8833-ThermalCamera (Note: This is just a source of inspiration. The schematics, PCB, panels, and shells of this project are all designed and made by myself! )
4. Except for the AMG8833 module, LCD screen, lithium battery and screws and nuts, all the physical objects are provided by Lichuang, including but not limited to components, PCB/SMT, panels, 3D shells...

lithium battery & screws & nuts: The previous inventory does not include links here. The screw specification is M2 length 20mm, and the lithium battery is 3.7V.
After deducting the above components (more than one hundred RMB ::> <:: ), the remaining cost of the entire project does not exceed 20RMB with the strong support of Lichuang. Thank you again for Lichuang's strong support! ! !

Project function introduction

Infrared thermal imaging camera is used to display circuit board temperature imaging, equipment temperature imaging, etc.
Originally, I wanted to make a thermal imager like the ones at the entrances and exits of high-speed trains that can detect body temperature. However, due to the poor performance of the AMG8833, I switched to an instrument that displays the temperature of circuit boards or equipment. The specific functions are expected to be as follows
1. Temperature imaging (core function)
2. Multiple display modes, such as: iron red, rainbow, white heat, etc.
3. Ultra-high or ultra-low temperature wake-up and alarm function
4. Lithium battery power detection

Hardware description

The schematic diagram and PCB can be opened directly in EasyEDA. The functions of each part of the schematic diagram are also marked, so I won’t explain them too much here. Below are the physical pictures after SMT and the complete circuit board diagram:
