Hey guys, im going to be using a pt100 with my pic to control a heater.
I am aware of the wheatstone bridge configuration however i have seen a-lot of layouts with op-amps.
The only op amp i have is a TI opa2132a which i have used previously for audio applications many years ago.
I wasn't sure this op-amp would be suitable for boosting the voltage from the wheatstone bridge.
Is it possible to get good result without amplification?
Also, could someone please explain how i would set up my bridge to measure a temperature between 0-250c and output a voltage between 0-5V for my pics ADC?
Thanks for reading!
