1.Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference.2.This protuct does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input.3.This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry,4.Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard).Description1. measurement temperature range: minus 200 degrees Celsius to 1350 degrees Celsius above 2. SPI interfaces, high-speed transmission3. the input voltage is 3-5v DC4. direct digital output temperature value, no amplifiers, no ADC5. 14-bit resolution, 0.25 degree temperature accuracyNote1.Works with any K type thermocouple2 K thermocouples have about 2C to 6C accuracy3.Internal temperature reading 4. 3 to 5v supply and logic level compliant 5. SPI data output requires any 3 digital I/O pins.Material: PC+Metalcolour: as shownPackage Contents:1 x MAX6675 ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
