It works with Arduino and ESP32 boards using the MAX31865 module. It can also be read directly by high‑resolution ADCs on microcontrollers like the Raspberry Pi Pico. For Raspberry Pi single‑board computers, use a dedicated RTD HAT or SPI module.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eUse a 3‑wire or 4‑wire connection to eliminate lead resistance errors. With the MAX31865 breakout, connect the two red wires to RTD+ and RTD−, and the white wire to the FORCE or RTD− reference. Ensure the reference resistor matches 430 Ω for optimal measurement. Avoid running sensor cables near high‑voltage lines.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
