The MAX6675 module communicates via a standard SPI interface (SCK, CS, SO pins), making it directly compatible with Arduino Uno, Nano, Mega, and most other Arduino boards. Simply connect the 5 pins and use a widely available MAX6675 library to start reading temperatures in minutes.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum temperature the included K-type thermocouple can measure?\u003c\/h4\u003e\n\u003cp\u003eA: The included K-type thermocouple is rated for up to 800°C. While the MAX6675 chip itself supports readings up to 1024°C, exceeding 800°C with the included thermocouple may result in inaccurate measurements or damage. For temperatures above 800°C, a separately rated high-temperature thermocouple is recommended.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this module work with 3.3V systems like Raspberry Pi or ESP32?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The MAX6675 module supports a wide supply voltage range of 3.0V to 5.5V DC, making it fully compatible with both 3.3V systems (Raspberry Pi, ESP32, ESP8266) and 5V systems (Arduino Uno, Mega).\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the module detect thermocouple disconnection?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The MAX6675 chip includes built-in thermocouple disconnection detection. If the thermocouple becomes open-circuited or disconnected, the module will output a specific fault value so your code can detect and handle the error gracefully.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is the MAX6675 temperature sensor module compatible with Arduino?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
