This tiny accessory gave my Android phone thermal vision superpowers. Here's how to use it
Briefly

The InfiRay P2 Pro consists of a tiny thermal camera and a magnetic snap-on macro lens that allows the camera to be brought super close to the item being examined.
The camera is indeed tiny. Measuring 27 × 18 × 9.8mm and weighing in at a minute 9 grams, it's smaller and lighter than a charging cable.
Setting up the P2 Pro is easy -- download and install the P2 Pro app from the Google Play Store, fire up the app, pop the camera into the USB-C port, and away you go.
Popping the macro lens onto the front of the camera lets you get up close and personal with what you're looking at, giving you better resolving power to really home in.
