AW: [En-Nut-Discussion] PT100 Sensor on ethernut

Hello James,

sorry, I missed to mention these detailes... I only want to measure a
temperature between -10°C and +120°C with a resolution of 0.5°C is 
sufficient. I also don't need any type of correction other than the one 
I can do in software.

I would appreciate a simple design using some simple operational 
amplifier like lm324.

I need to measure four temperatures at the same time and need long 
distances between the sensor and the ethernut board (min. 3 meter).

As an alternative the ds1822 seem a good idea, but I would need it in a 
"closed" design. If it's not available I would need to construct 
something by my self.

Best regards,

Ole Reinhardt
