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). Description 1. measurement temperature range: minus 200 degrees Celsius to 1350 degrees Celsius above zero 2. SPI interfaces, high-speed transmission 3. the input voltage is 3-5v DC 4. direct digital output temperature value, no amplifiers, no ADC 5. 14-bit resolution, 0.25 degree temperature accuracy Note 1.Works with any K type thermocouple 2 K thermocouples have about ±2°C to ±6°C accuracy 4.Internal temperature reading 5.3 to 5v power supply and logic level compliant! 6.SPI data output requires any 3 digital I/O pins.
