The thermal camera is a
FLIR ONE. It was $250. The Consumer Electronics show is going on right now, and FLIR is showing off the next generation version of the same camera, coming out later this year, which will of course be even better.
FLIR ONE and
SEEK are the two main inexpensive smartphone thermal cameras out there right now.
I've been having lots of fun with it. It's very interesting to see heat. I'll be using this on some solar projects and anything else I can think of.
