IR Themometer

[boose1874]

I need to build a IR themometer.....
I still have a lot of problem about....
(e.g. What senser can I use to sense the amount of IR emit from an object...)
I still have no idea in this topic....
Should any one can give me a hand???

There are several types of noncontact temp sensors. They all work based on a simple principle: Planck's Law of the thermal emission of radiation.
