Yes that's the one. I couldn't remember/be bothered to check
Thermal camera would only work if there was a surface to get the temperature of, we needed to know the temperature of the air in the middle of the room rather than the walls etc.
We did think about hanging ping pong balls on string like the sensors I hung but then yes, accuracy becomes an issue compared to the ds18b20.
Also this was in 2011 so I don't think we had the same variety of embedded device compatible stuff available and a proper thermal camera was out of our budget.
Fun side note, I brought the test rig back to life a few months ago for fun, found the OneWire lib code I wrote, copied into the Arduino project (mBed was long gone) and it worked with about 2 minutes of tweaking. That's 13 year old code up and running like no time had passed ... I can't even imagine the pain of bringing back a 13 year old web project!
