OVERVIEW: A wireless temperature sensor employing 8 three wire PT100 RTDs transmitting the acquired data using Bluetooth. The aim of this project was to measure and wirelessly transmit temperature ...

Circuit simulation made easy. A free online environment where users can create, ... the one at the bottom is represented by the PT100 sensor and the one at the top by a precision resistor. Figure 6 ...

This post also details the math behind the circuit design and should be a good read. The Arduino sketch does not rely on PT100RTD library mentioned above, and is much simpler, but note the circuit ...
