This post will cover how to use the Melexis MLX90640 thermal array sensor with the ESP32-Cam module. The work presented here is based off of the work of others and their documented efforts. The reason for using the ESP32-Cam module is because of its low cost, small form factor, and its built in microSD storage. The Melexis MLX90640 thermal array sensor can provide a 32 x 24 pixel thermal image in either a 55 or 110 degree field of view…
Near IR has been covered in earlier posts and I wanted to expand on the topic after seeing it represented in false color. I happened upon Mathieu Stern’s work a couple of weeks after my last post, which he posted just over three weeks earlier. The commercial grade work employed a yellow filter inserted in a modified high end camera that had its Near IR filter removed by Kolari Vision. This second video expanded on the topic. The filter manufacturer…

I concluded that purpose-built lenses were better suited. Since this was the case, I opted to order a NOIR filtered lens for my RunCam2 4K camera. This would give me more “ready to use” features than coding another project for the ESP32-Cam. The lens I found online was for a CCTV camera with the following specs, 5MP…
