Oct 2, 2004 · In your opinion which is the best way to interface PT100 to an A/D Pic16f876 port? is there any IC suitable? how can I filter PT100 signal to have a good temperature sensor? is there any trick? Your PIC has 10-bit A/D, what represents 1024 levels (≈0.0049mV per level).

Mar 4, 2014 · so how to interface pt100 with PIC. Look at this data sheet pdf [last page] and the LTSpice sim circuit for options. Ask if you have a problem. All PT100 sensors are 2 wire, it's the wires to the sensor that can be 2, 3 or 4. Since the resistance change is small, one has to compensate the lead resistance.

May 24, 2006 · This circuit [pt100-precision-interface...] is designed to work as an instrumentation amplifier, and some of opamps’ inputs work with voltages very close to 0V/GND. For that one needs a rail-to-rail opamp.

Jan 3, 2010 · I want to display and control (on/off control) temperature using pt100 as sensor and pic16f877A. I built 1mA current source using lm324 quad operational...

Sep 28, 2008 · A PIC is incapable of reading an RTD directly. There are chips made for this; I don't remember who, but I'd check Burr-Brown, Analog Devices, and Dallas-Maxim. If you …

Jul 27, 2008 · je suis à la recherche d'un circuit intégré qui conditionnerait une sonde PT100 pour l'interfacer directement avec un micro controleur PIC: donc sortie analog, logique, pwm...

Jul 5, 2005 · Can anybody give me any hints ideas or circuits to allow me to read the temperature from a Pt100 RTD probe in to a PIC microcontroller? Regards, Mark

Sep 16, 2011 · I am required to connect a PT100 2-wire thin film sensor to a PIC16F877A. I am connecting the sensor to RA0 of the PIC. But it seems like my PIC is not getting any readings.

Oct 5, 2007 · 1.2 what is the pt100 rtd evaluation board? The PT100 RTD Evaluation Board demonstrates how to bias a Resistive Temperature Detector (RTD) and accurately measure temperature.
