In this video, I test the GOYOJO GW340 thermal camera, a compact smartphone thermal imaging attachment designed for both Android and iPhone. I go through the specifications, unboxing, and take a closer look at the mobile application.
Then I move on to real-world examples, including testing several 3D printer heated beds to check temperature distribution and cold spots. This is a practical use case where a small thermal camera can quickly show issues that are hard to see otherwise.
Is the GOYOJO GW340 a genuinely useful tool for makers and engineers, or just a nice-looking gadget? Let’s find out.
