It requires a thermocouple amplifier such as MAX31855 (J-type variant) or AD8495 for direct interfacing with Arduino, Raspberry Pi, or ESP32. Works with any microcontroller that can read analog voltage with appropriate amplification.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eThe red wire is the negative lead and the other color (commonly white or blue) is positive. Connect to a thermocouple amplifier's input terminals, ensuring tight connections to avoid noise. For direct analog reading, a low-noise instrumentation amplifier is recommended.\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.
