{"product_id":"pl4-sen-13266","title":"Thermocouple Breakout - MAX31855K","description":"\u003cp\u003eThe SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution, SPI-compatible, serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a 'hot' end and a 'cold' one). Once this is achieved, a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end, digitizes the temperature measured and sends that data out the other end via a SPI interface, thereby interpreting the data and translating it for you to read!\u003c\/p\u003e\n\n\u003cp\u003eWith the SparkFun Thermocouple Breakout, the thermocouples hot junction can be read from -200°C to +700°C with an accuracy of ±2°C while the cold junction, inside the MAX31855K, can only range from -20°C to +85°C while maintaining ±2°C accuracy. The MAX31855K constantly measures the temperature of the cold junction using an internal temperature-sensing diode. The MAX31855K requires a power source from +3.0V to +3.6V (+3.0V nominal) and only draws 1.5mA maximum.\u003c\/p\u003e\n\n\u003cp\u003eThe Thermocouple Breakout is designed to accept a standard [thermocouple connector](https:\/\/www.sparkfun.com\/products\/13612), for convenience and compatibility with probes you may already own. These connectors arent necessary, and you could solder a thermocouple directly into the through-holes labeled ˜+ and ˜-. If you decide to solder the thermocouple directly to the breakout board, it is recommended that the thermocouple be mounted for strain relief to avoid breaking the thin wires. Notches for a zip-tie or wire wrapping have been provided in the PCB opposite the header for this purpose.\u003c\/p\u003e\n\n\u003cp\u003e**Features:**\u003c\/p\u003e\n\n\u003cp\u003e* 14-bit Resolution\u003cbr\u003e\n* SPI-Compatible, Serial Interface\u003cbr\u003e\n* -200°C to +700°C Temperature Reading with ±2°C Accuracy\u003cbr\u003e\n* 3.0V to 3.6V (+3.0V nominal) Required\u003cbr\u003e\n* Accepts Type-K Thermocouple\u003c\/p\u003e\n\n\u003cp\u003e**Documents:**\u003c\/p\u003e\n\n\u003cp\u003e* [Schematic](https:\/\/cdn.sparkfun.com\/datasheets\/Sensors\/Temp\/SparkFun_Thermocouple_Breakout_v10.pdf)\u003cbr\u003e\n* [Eagle Files](https:\/\/cdn.sparkfun.com\/datasheets\/Sensors\/Temp\/SparkFun_Thermocouple_Breakout_v10.zip)\u003cbr\u003e\n* [Hookup Guide](https:\/\/learn.sparkfun.com\/tutorials\/max31855k-thermocouple-breakout-hookup-guide)\u003cbr\u003e\n* [Datasheet](https:\/\/cdn.sparkfun.com\/datasheets\/Sensors\/Temp\/MAX31855K.pdf) (MAX31855K)\u003cbr\u003e\n* [GitHub](https:\/\/github.com\/sparkfun\/MAX31855K_Thermocouple_Breakout) (Design Files)\u003cbr\u003e\n* [GitHub](https:\/\/github.com\/sparkfun\/SparkFun_MAX31855K_Thermocouple_Breakout_Arduino_Library) (Library \u0026amp; Example Code)\u003c\/p\u003e\n\n\u003cp\u003e**Videos**\u003c\/p\u003e","brand":"SparkFun","offers":[{"title":"Default Title","offer_id":39690156048565,"sku":"PL4-SEN-13266","price":54.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/13266-01.jpg?v=1618122204","url":"https:\/\/getcahits.com\/zh\/products\/pl4-sen-13266","provider":"PuriLite","version":"1.0","type":"link"}
