Hi all

First let me say... this is a peripheral for a Pic application. I don't want
to be attacked for off topic questions.

I just bought a circuit for an optical pyrometer. The circuit has no
explanation. It gives a partial billmat. It shows as a source an IR Pass and
an IR stop symbol, but doesn't provide any part numbers. I am not sure how
this is suppose to work. I am trying to build an IR temp sensor and I hoped
that this circuit would provide some insight. It appears that the output is
1-5 mA, but doesn't explain anything.

I would be happy to send the circuit to any interested party who could help
me understand how it works.

Thanks in advance


Jon
