I need to display the temperature from a thermistor or other probe type onto a set of 7 segment displays, problem is I have no experience with programming micro-controllers. I need to display the temp between about 0 to 200 degrees F. Is there a simple circuit to accomplish this or maybe something similar made by a manufacturer?

 

There are some temperature sensors that have an output in millivolts/degree. For example if the temperature is 72 degrees the output would be 72 millivolts. Connecting directly to a small 3 1/2 digit digital voltmeter the temperature reads directly in volts. If this would be helpfull I can get more specific about parts and connections.

 

It needs to be a stand-alone circuit from temperature probe to readout because it will be permanently mounted for continuous operation monitoring. It would be nice to have a high temp warning light come on at a certain temp but I will worry about this once I am able to actually see the temperature.

 

A typical meter like this one http://www.mpja.com/prodinfo.asp?number=16177+ME
With a temperture probe like a national semiconductor LM34 and a power source is all you would need.

 

Ah, thank you very much, I should be able to find one of these to fit the bill.
