Good Day,
I have a simple temperature measuring system using a LM35 temperature sensor and a PIC16F690 micro controller interfaced to a 3 digit 7 segment led display.
I currently have the senor connected to a Analog pin (via a opamp), using A2D to sample. I was wondering how I could implement a simple offset adjustment in between the sensor and the pic?
I know that one could interface a trim-pot onto another Analog channel and use software correction, but I am wondering if there exists a simple hardware solution?
Thanks for the assistance,
