Guys,

I've noticed quite a few posts discussing RTD's and implementing them to a Microcontroller by use of buffer/differential amps. My question is do you really need the buffering? Can I not just add the RTD as a voltage divider circuit to the micro to provide the voltage swing to the Micro?

Kind Regards,
Ringo
 

I think its not possible to connect RTD with voltage divider & to micro.. Because that resistance variations Vs temperature is not uniform & big..
better u go threw this link.. & hope You ll got better idea...
