Expert Design for 3-Wire Pt100 Interface Circuit with 3.3v Microcontroller Compatibility

Published on the August 08, 2026 in Engineering & Manufacturing

About this project

Open

We are seeking an experienced electronics engineer to design a robust and accurate 3-wire PT100 interface circuit. The primary requirement is that the output of this circuit must be fully compatible with a 3.3V microcontroller, allowing for straightforward integration. The circuit should provide an output signal that can be reliably and linearly converted to degrees Celsius by the microcontroller. The design should prioritize accuracy, stability, and ease of temperature calculation. Consideration for noise immunity and efficient power consumption would be a plus. The final deliverable will be a detailed circuit schematic and potentially a bill of materials.
