IR Temperature Sensors? ?
Archiver
Posts: 46,084
I have been racking my brain.. I am trying to build a non contact
temperature screening device. IR is the 1st thought, but with IR
sensors the width of the temp area changes with the distance from the
surface. Thats the killer.. the surface is uneven. So I am trying to
precisely measure the temp in several areas on an uneven surface at
the same time (or near same time). Is IR the answer, is there an IR
temp sensor that has a fixed width. Should I look at a different
sensor? Can you measure Temp with Fiber or laser?
Thanks

interface (needs a BS2p or BS2pe for 1-Wire). This kit comes with K, J,
and T thermocouple elements.

to "attach" to the surface. Spacing, adhesion, power source.. etc.
Essentially I am building a temperature matrix or mesh that transmits
temps to a datalogger in near real time. So if I put may hand under
the IR mesh, I would get temp values from maybe 50 "spots' on my
hand..
If I could measure Temp changes with fiber I could build a glove
Thanks

couple of mirrors (off of steppers?).
You could then just fire the IR beam into the first mirror and have the
stamp 'advance' the motor across a series of points that would then be read
back.
Question then is how to get the data out of one of these IR temp guns....a
bit of reverse engineering...??

Pretty much, I run into a whole new set of issues when trying
to "attach" to the surface. Spacing, adhesion, power source.. etc.
Essentially I am building a temperature matrix or mesh that transmits
temps to a datalogger in near real time. So if I put may hand under
the IR mesh, I would get temp values from maybe 50 "spots' on my
