Reading temperature remotely
Basically I want to a circuit that lights up a light if a certain area is over 50C. Would an IR sensor pointed at the location work? Or is something else needed. It doesn't need to be accurate, just good enough.

Re: Reading temperature remotely
IR sensors, at least the ones you find here and on sites like this one, are mostly confined to motion sensing. They don't report temperature like the ones I think you're talking about.
I assume putting a circuit into your > 50° C area is out of the question because it's > 50° C in there. But could you tolerate a thermocouple stuck in there?

Re: Reading temperature remotely
Well, the idea was for it to be non-contact. And yes, I was thinking about an infrared thermometer. I just don't need to accuracy (and the expense) of a thermometer though.

Re: Reading temperature remotely
Pololu has an IR temp sensorfor about $20. The FOV is 90 degrees, but you could probably narrow that a bit with some optics.
A thermocouple plus an amplifier will run you $27.50.
The TMP36 sensor is good to 150C and only costs $2.

Re: Reading temperature remotely
You could use a Melexis non contact sensor.
